On containerized deployment, the OSD entrypoint runs some ceph-volume
commands (lvm/simple scan and/or activate) which perform badly without
the ulimit option.
This option was added for all previous ceph-volume commands but not on
the ceph-osd container startup.
Also updating hard limit value to 4096 to reflect default baremetal
value.

Otherwise it will fail when running rolling_update.yml playbook because
of `serial: 1` usage.
The task which copies the script is run against the current node being
played only whereas the task which runs the script is run against all
nodes in a loop, it ends up with the typical error:

When using containerized deployment we have to create the systemd
service unit based on a template.
The current implementation with ceph-disk is using the device name
as paramater to the systemd service and for the container name too.
$ systemctl start ceph-osd@sdb
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE NAMES
065530d0a27f ceph/daemon:latest-luminous ceph-osd-strg0-sdb
This is the only scenario (compared to non containerized or
ceph-volume based deployment) that isn't using the OSD id.
$ systemctl start ceph-osd@0
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE NAMES
d34552ec157e ceph/daemon:latest-luminous ceph-osd-0
Also if the device mapping doesn't persist to system reboot (ie sdb
might be remapped to sde) then the OSD service won't come back after
the reboot.
This patch allows to use the OSD id with the ceph-osd systemd service
but requires to activate the OSD manually with ceph-disk first in
order to affect the ID to that OSD.

The ceph-volume lvm list command takes ages to complete when having
a lot of LV devices on containerized deployment.
For instance, with 25 OSDs on a node it takes 3 mins 44s to list the
OSD.
Adding the max open files limit to the container engine cli when
executing the ceph-volume command seems to improve a lot thee
execution time ~30s.
This was impacting the OSDs creation with ceph-volume (both filestore
and bluestore) when using multiple LV devices.

Since all files in container image have moved to `/opt/ceph-container`
this check must look for new AND the old path so it's backward
compatible. Otherwise it could end up by templating an inconsistent
`ceph-osd-run.sh`.

since `ceph-volume` introduction, there is no need to split those tasks.
Let's refact this part of the code so it's clearer.
By the way, this was breaking rolling_update.yml when `openstack_config:
true` playbook because nothing ensured OSDs were started in ceph-osd role (In
`openstack_config.yml` there is a check ensuring all OSD are UP which was
obviously failing) and resulted with OSDs on the last OSD node not started
anyway.

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.

Description of problem: The 'get osd id' task goes through all the 10 times (and its respective timeouts) to make sure that the number of OSDs in the osd directory match the number of devices.
This happens always, regardless if the setup and deployment is correct.
Version-Release number of selected component (if applicable): Surely the latest. But any ceph-ansible version that contains ceph-volume support is affected.
How reproducible: 100%
Steps to Reproduce:
1. Use ceph-volume (LVM) to deploy OSDs
2. Avoid using anything in the 'devices' section
3. Deploy the cluster
Actual results:

Expected results:
There aren't any (or just a few) timeouts while the OSDs are found
Additional info:
This is happening because the check is mapping the number of "devices" defined for ceph-disk (in this case it would be 0) to match the number of OSDs found.
Basically this line:
until: osd_id.stdout_lines|length == devices|unique|length
Means in this 2 OSD case it is trying to ensure the following incorrect condition:
until: 2 == 0

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.
When Ansible is not run with verbose options it's difficult to see which
include and/or set_fact does what. So adding a name for each clarifies.

The script can fail to get the osd id because the osds are activated by
udev and it can take a while for them to activate. This commit fixes
that by trying to get all the osds per node in a loop.
This commit also makes the osd services enabled so that they are
available after reboot.

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
