Since we do not have enough data to put valid upper bounds for the memory
usage of these daemons, do not put artificial limits by default. This will
help us avoid failures like OOM kills due to low default values.
Whenever required, these limits can be manually enforced by the user.

If this is set to anything other than the default value of 1 then the
--osds-per-device flag will be used by the batch command to define how
many osds will be created per device.

This is used with the lvm osd scenario. When using devices you need the
option to set the crush device class for all of the OSDs that are
created from those devices.

As discussed with the cores, the current limits are too low and should
be bumped to higher value.
So now by default monitors get 3GB and OSDs get 5GB.

This was causing a lot of pain with the handlers. Also the
implementation was not ideal since we were assembling files. Everything
can now be done with the ceph_crush module so let's remove that.

This is to keep backward compatibility with stable-2.2 and satisfy the
check "verify dedicated devices have been provided" in
`check_mandatory_vars.yml`. This check is looking for
`dedicated_devices` so we need to default it's value to
`raw_journal_devices` when `raw_multi_journal` is set to `True`.

Add the variables ceph_osd_docker_cpuset_cpus and
ceph_osd_docker_cpuset_mems, so that a user may specify
the CPUs and memory nodes of NUMA systems on which OSD
containers are run.
Provides a example in osds.yaml.sample to guide user
based on sample `lscpu` output since cpuset-mems refers
to the memory by NUMA node only while cpuset-cpus can
refer to individual vCPUs within a NUMA node.
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.

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.

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:
osd_objectstore: bluestore
bluestore: true
Now you just need to set `osd_objectstore: bluestore`.

Oh yeah! This patch adds more fine grained control on how we run the
activation osd container. We now use --device to give a read, write and
mknodaccess to a specific device to be consumed by Ceph. We also use
SYS_ADMIN cap to allow mount operations, ceph-disk needs to temporary
mount the osd data directory during the activation sequence.
This patch also enables the support of dedicated journal devices when
deploying ceph-docker with ceph-ansible.

We changed the way we declare image.
Prior to this patch we must have a "user/image:tag"
format, which is incompatible with non docker-hub registry where you
usually don't have a "user". On the docker hub a "user" is also
identified as a namespace, so for Ceph the user was "ceph".
Variables have been simplified with only:
* ceph_docker_image
* ceph_docker_image_tag
1. For docker hub images: ceph_docker_name: "ceph/daemon" will give
you the 'daemon' image of the 'ceph' user.
2. For non docker hub images: ceph_docker_name: "daemon" will simply
give you the "daemon" image.
Infrastructure playbooks have been modified as well.
The file group_vars/all.docker.yml.sample has been removed as well.
It is hard to maintain since we have to generate it manually. If
you want to configure specific variables for a specific daemon simply
edit group_vars/$DAEMON.yml

Prior to this patch we had several ways to runs containers, we could use
ansible's docker module on some distro and on containers distros we were
using systemd. We strongly believe threating containers as services with
systemd is the right approach so this patch generalizes to all the
distros. These days most of the distros are running systemd so it's fair
assumption.
