Sébastien Han 18402b636f defaults: add useful info if daemon are not restarted properly
If OSDs don't restart normally we now also dump info of the crush map,
crush rules, crush tree and pools.

If the monitors don't restart normally we also print the socket status
by calling mon_status and quorum_status.

Andy McCrae 60d4b75f51 Cleanup plugins directories and references
Having callback_plugins, and action plugins in random locations causes
a lot of disparity.

We should centralize this into one place in the plugins directory and
fix up the ansible.cfg to reflect this.

Additionally, since the ansible.cfg already reflects action_plugins, we
don't need a link to action_plugins in the base of the repository.

Guillaume Abrioux 9181c94adf client: fix pgs num for client pool creation
The `pools` dict defined in `roles/ceph-client/defaults/main.yml`
shouldn't have `{{ ceph_conf_overrides.global.osd_pool_default_pg_num
}}` as default value for `pgs` keys.

For instance, if you want some pools to be created but without explicitely
specifying the pgs for these pools (it means you want to use the
`osd_pool_default_pg_num`), you will be obliged to define
`{{ ceph_conf_overrides.global.osd_pool_default_pg_num }}` anyway while you
wanted to use the current default value already defined in the cluster which is
retrieved early in the playbook and stored in the
`{{ osd_pool_default_pg_num }}` fact.

Sébastien Han a52ed43093 mon: fix osd_pool_default_crush_rule persistence and effectiveness
Running the last portion (insert new default and add new default crush
tasks) of crush_rules.yml only on the last monitor is
wrong since ceph CLI calls usually end up on the master having the
quorum, which is by default the one with the lower IP.
So if we run the  command and end up on another mon the creation will
happen on the default crush rule because the particular mon hasn't been
updated.
To fix this we remove the |last on the include and use run_once: true on
 certain tasks, then we let the final two tasks run on all the monitors.

Sébastien Han 5fac3784f7 add ceph_crush module
This module allows us to create Ceph CRUSH hierarchy. The module works
with
hostvars from individual OSD hosts.
Here is an example of the expected configuration in the inventory file:

[osds]
ceph-osd-01 osd_crush_location="{ 'root': 'mon-roottt', 'rack':
'mon-rackkkk', 'pod': 'monpod', 'host': 'localhost' }"  # valid case

Then, if create_crush_tree is enabled the module will create the
appropriate CRUSH buckets and their types in Ceph.

Some pre-requesites:

* a 'host' bucket must be defined
* at least two buckets must be defined (this includes the 'host')

Sébastien Han f2e0ceed78 add support for installation checkpoint
This was taken from the openshift ansible repository here:
https://github.com/leseb/openshift-ansible/tree/master/roles/installer_checkpoint

Rationale:

A complete OpenShift cluster installation is comprised of many different
components which can take 30 minutes to several hours to complete. If
the installation should fail, it could be confusing to understand at
which component the failure occurred. Additionally, it may be desired to
re-run only the component which failed instead of starting over from the
beginning. Components which came after the failed component would also
need to be run individually.

Ceph has a similar situation so we can benefit from that
callback_plugin.

Guillaume Abrioux 4a8986459f tests: change ceph_docker_image_tag for 2nd run
The ceph-ansible upstream CI runs severals tests, including a
'idempotency/handlers' test. It means the playbook is run a first time
and then a second time with an other container image version to ensure the
handlers run properly and the containers are well restarted.
This can cause issues.
For instance, in that specific case which drove me to submit this commit,
I've hit the case where `latest` image ships ceph 12.2.3 while the `stable-3.0`
(which is the image used for the second run) ships ceph 12.2.2.

The goal of this test is not to verify we can upgrade from a specific
version to another but to ensure handlers are working even if it's a valid
failure here.
It should be caught by a test dedicated to that usecase.

We just need to have a container image which has a different id for
the upstream CI, we need the same content in container imagebut a different
image id in the registry since the test relies on image id to decide whether
the container should be restarted.

Andy McCrae 59a4335a56 Restart services if handler called
This patch fixes an issue where if hosts have different service lists,
it will prevent restarting changes on services that run later on.

For example, hostA in the mons and rgws group would initiate a config
change and restart of services on all mons and rgws hosts, even though
a separate hostB (which is only in the rgws group) has not had its
configuration changed yet. Additionally, when the second host has its
coniguration changed as part of the ceph-rgw role, it will not initiate
a restart since its inventory name != the first hosts.

To fix this we should run the restart once (using run_once: True)
as long as the host has called the handler. This will ensure that even
if only 1 host has called the handler it will initiate a restart on all
hosts that have called the handler.

Additionally, we add a var that is set when the handler runs, this will
ensure that only hosts that have called the handler get restarted.

Includes minor fix to remove unrequired "inventory_hostname in
play_hosts" when: clause. This is no longer required since the handlers
were changed. The host calling the handler will be in play_hosts
already.

Guillaume Abrioux e537779bb3 osd: fix osd restart when dmcrypt
This commit fixes a bug that occurs especially for dmcrypt scenarios.

There is an issue where the 'disk_list' container can't reach the ceph
cluster because it's not launched with `--net=host`.

If this container can't reach the cluster, it will hang on this step
(when trying to retrieve the dm-crypt key) :

```
+common_functions.sh:448: open_encrypted_part(): ceph --cluster abc12 --name \
client.osd-lockbox.9138767f-7445-49e0-baad-35e19adca8bb --keyring \
/var/lib/ceph/osd-lockbox/9138767f-7445-49e0-baad-35e19adca8bb/keyring \
config-key get dm-crypt/osd/9138767f-7445-49e0-baad-35e19adca8bb/luks
+common_functions.sh:452: open_encrypted_part(): base64 -d

-luksOpen /dev/sdb1 9138767f-7445-49e0-baad-35e19adca8bb
```

It means the `ceph-run-osd.sh` script won't be able to start the
`osd_disk_activate` process in ceph-container because he won't have
filled the `$DOCKER_ENV` environment variable properly.

Adding `--net=host` to the 'disk_list' container fixes this issue.
