Sometimes it's useful to be able to skip the OSD creation step when
running ceph-ansible (cf #1777). The lvm scenario has a prepare_osd
tag on the relevant play. This commit adds the same tag to the
lvm-batch scenario.

Otherwise this will generate an ansible warning about the missing
filter.
[DEPRECATION WARNING]: evaluating xxx as a bare variable, this behaviour
will go away and you might need to add |bool to the expression in the
future.

be removed in version 2.12.

ceph-volume can generate large logs at some point.
debug logs by definition should be enabled only when debugging.
Let's make it customizable with a variable which is set to `False` by

Since https://github.com/ceph/ceph/commit/77912c0 ceph-volume uses
stdout encoding based on LC_CTYPE and PYTHONIOENCODING environment
variables.
Thoses variables aren't set when using ansible.
Currently this commit breaks non containerized deployment on Ubuntu.
TASK [use ceph-volume to create bluestore osds] ********************
cmd:
- ceph-volume
- --cluster
- ceph
- lvm
- create
- --bluestore
- --data
- /dev/sdb
rc: 1
stderr: |-
Traceback (most recent call last):

Note that the task is failing on ansible side due to the stdout
decoding but the osd creation is successful.

This commit does a couple of things:
* Avoid code duplication
* Clarify the code
* add more unit tests
* add myself to the author of the module

The batch option got recently added, while rebasing this patch it was
necessary to implement it. So now, the batch option can work on
containerized environments.

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.

This adds the action 'batch' to the ceph-volume module so that we can
run the new 'ceph-volume lvm batch' subcommand. A functional test is
also included.
If devices is defind and osd_scenario is lvm then the 'ceph-volume lvm
batch' command will be used to create the OSDs.

We know bindmount with the :z option at the end of the -v command so
this will basically run the exact same command as we used to run. So to
speak:

Regardless if the partition is 'ceph' or something else, we don't want
to be as strick as checking for a particular partition.
If the drive has a partition, we just don't do anything.
This solves the case where the server reboots, disks get a different
/dev/sda (node) allocation. In this case, prior to restarting the server
/dev/sda was an OSD, but now it's /dev/sdb and the other way around.
In such scenario, we will try to prepare the OSD and create a new
partition, so let's not mess around with devices that have partitions.

Use `devices` variable instead of `ansible_devices`, otherwise it means
we are not using the devices which have been 'auto discovered'

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.

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.

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
always numbered 1, we take the min element of the dict.

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
