During the initial implementation of this 'old' thing we were falling
into this issue without noticing
https://github.com/moby/moby/issues/30341 and where blindly using --rm,
now this is fixed the prepare container disappears and thus activation
fail.
I'm fixing this for old jewel images.
Also this fixes the machine reboot case where the docker logs are
purgend. In the old scenario, we now store the log locally in the same
directory as the ceph-osd-run.sh script.

Use "ceph_tcmalloc_max_total_thread_cache" to set the
TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES value inside /etc/default/ceph for
Debian installs, or /etc/sysconfig/ceph for Red Hat/CentOS installs.
By default this is set to 0, so the default package value will be used,
if specified this value will be changed to match the variable, and ceph
osd services will be restarted.
There was a huge resync from luminous to jewel in ceph-docker:
https://github.com/ceph/ceph-docker/pull/797
This change brought a new handy function to discover partitions tight to
an OSD. This function doesn't exist in the old image so the
ceph-osd-run.sh script breaks when trying to deploy Jewel OSD with that
old Jewel image version.

stable-3.0 brought numerous changes in ceph-ansible variables, this PR
aims to maintain backward compatibility for someone running stable-2.2
upgrading to stable-3.0 but keeps its groups_vars untouched.
We will then determine the right options to make sure the upgrade works
but we are expecting that new variables should be used.
We will drop this in a near future, maybe 3.1 or 3.2.

This commit add new osd scenarios, it aims to simplify the CI setup and
brings a better coverage on the OSD scenarios.
We decided to differentiate between filestore and bluestore, thinking
ahead when filestore won't be supported anymore.
So we now have two classes of tests:
* Filestore
* Bluestore
In each of those classes we have container and non-container.
Then for each we test the following:
* collocated
* collocated dmcrypt
* non-collocated
* non-collocated dmcrypt
* auto discovery collocated
* auto discovery collocated dmcrypt
This gives us a nice coverage and also reduces the footprint on the CI.
We are now up to 4 scenarios, each containing 6 OSD VMs.

Closes-bug: #2056
This patch changes the `when:` keys so that they have no jinja2
delimiters. This avoids Ansible warnings which could turn into
errors in a future Ansible release.
The `always_run` key is deprecated and being removed in Ansible 2.4.
Using it causes a warning to be displayed:
[DEPRECATION WARNING]: always_run is deprecated.
This patch changes all instances of `always_run` to use the `always`
tag, which causes the task to run each time the playbook runs.
This is causing unknown issues when trying to start a dmcrypt container.
Basically the container is stuck at mount opening the LUKS device. This
is still unknown why this is causing trouble but we need to move
forward. Also, this doesn't seem to help in any ways to fix the race
condition we've seen.

It's sad but we can not rely on the prepare container anymore since the
log are flushed after reboot. So inpecting the container does not return
anything.
Now, instead we use a ephemeral container to look up for the
journal/block.db/block.wal (depending if filestore or bluestore) and
build the activate command accordingly.

We generate the ceph.conf on all the nodes through the
ceph-docker-common so there is no need to push it to the Ansible file.
Also this is breaking the ceph.conf template generation since we only
generate sections based on the host the ansible task is running on.
For example, what's typically happening, we bootstrap the monitor, we
get a ceph.conf generated for a mon only, we go on an osd, we generate
the ceph.conf with osd section (done by ceph-docker-common) but this
gets overwritten by the copy_config task of the ceph-osd role.

Prior to this patch this activation sequence for autodetection was
always skipped because we were asking to activate on device without
partitions, which doesn't make sense.
We also fix the way we lookup for a device, since the data partition is

The lvm_volumes variable is now a list of dictionaries that represent
each OSD you'd like to deploy using ceph-volume. Each dictionary must
have the following keys: data, journal and data_vg. Each dictionary also
can optionaly provide a journal_vg key.
The 'data' key represents the lv name used for the OSD and the 'data_vg'
key is the vg name that the given lv resides on. The 'journal' key is
either an lv, device or partition. The 'journal_vg' key is optional and
must be the vg name for the journal lv if given. This key is mainly used
for purging of the journal lv if purge-cluster.yml is run.
For example:
lvm_volumes:
- data: data_lv1
journal: journal_lv1
data_vg: vg1
journal_vg: vg2
- data: data_lv2
journal: /dev/sdc
data_vg: vg1

ceph services can fail to start under certain circumstances (for
example, when running in a container) because the default systemd
service configuration causes namespace issues.
To work around this we can override the system service settings by
placing an overrides file in the ceph-<service>@.service.d directory.
This can be generic so as to allow any potential changes required to
the ceph-<service> service files.
The overrides file is only setup when the
"ceph_<service>_systemd_overrides" config_template override variable is
specified.
The available service systemd override files are as follows:
ceph_mds_systemd_overrides
ceph_mgr_systemd_overrides
ceph_mon_systemd_overrides
ceph_osd_systemd_overrides
ceph_rbd_mirror_systemd_overrides
ceph_rgw_systemd_overrides
This scenario will create OSDs using ceph-volume and is only available
in ceph releases greater than Luminous.

We have multiple issues with ceph-disk's cli with bluestore and Ceph
releases. This is mainly due to cli changes with Luminous. Luminous
introduced a --bluestore and --filestore options which respectively does
not exist on releases older than Luminous. The default store being
bluestore on Luminous, simply checking for the store is not enough so we
have to build a specific command line for ceph-disk depending on the
Ceph version we are running and the desired osd_store.

This commits refactors how we deploy bluestore. We have existing
scenarios that we don't want to change too much. This commits eases the
user experience by now changing the way you use scenarios. Bluestore is
just a different interface to store objects but the scenarios more or
less remain the same.
If you set osd_objectstore == 'bluestore' along with
journal_collocation: true, you will get an OSD running bluestore with DB
and WAL partitions on the same device.
If you set osd_objectstore == 'bluestore' along with
raw_multi_journal: true, you will get an OSD running bluestore with a
dedicated drive for the rocksdb DB, then the remaining
drives (used with 'devices') will have WAL and DATA collocated.
If you set osd_objectstore == 'bluestore' along with
raw_multi_journal: true and declare bluestore_wal_devices you will get
an OSD running bluestore with a dedicated drive for rocksdb db, a
dedicated drive partition for rocksdb WAL and a dedicated drive for
DATA.

There is no need for 2 variables to enable bluestore, prior to this
patch one had to do the following to activate bluestore:
