Until now it was not possible to install a specific container package
because it was somehow hardcoded.
This patch allows to override the container package name (docker.io
vs docker-ce) and refacts the package installation. This could be
achieve via the container_package_name variable.
Instead of using one task per distribution we can set the package and
service name in vars. This allows to have a unified package task.
Also refactorize the debian_prerequisites tasks because the content
was outdated.

rgw: add cpuset support
1/ The OSD already supports cpuset to be used for containerized deployments
through the use of the ceph_osd_docker_cpuset_cpus variable. This adds similar
support to the RGW service for containerized deployments by setting a new
variable named ceph_rgw_docker_cpuset_cpus. Like the OSD, there are times where
using distinct cores has advantages over using the CFS in kernel scheduler.
ceph_rgw_docker_cpuset_cpus accepts a comma delimited set of CPU ids
2/ Add support for specifying --cpuset-mem variable to restrict the cgroup's memory
allocations to a particular numa node, which should typically correspond with
the cpu ids of that numa node that were provided with --cpuset-cpus. To ensure
the correct cpu ids are used one can run `numactl --hardware` to list the nodes
and which cpu ids correspond to each.

UCA: Uncomment UCA variables in defaults, fix consequent breakage
The Ubuntu Cloud Archive-related (UCA) defaults in
roles/ceph-defaults/defaults/main.yml were commented out, which means
if you set `ceph_repository` to "uca", you get undefined variable
errors, e.g.
```
The task includes an option with an undefined variable. The error was: 'ceph_stable_repo_uca' is undefined
The error appears to have been in '/nfs/users/nfs_m/mv3/software/ceph-ansible/roles/ceph-common/tasks/installs/debian_uca_repository.yml': line 6, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: add ubuntu cloud archive repository
^ here
```
Unfortunately, uncommenting these results in some other breakage,
because further roles were written that use the fact of
`ceph_stable_release_uca` being defined as a proxy for "we're using
UCA", so try and install packages from the bionic-updates/queens
release, for example, which doesn't work. So there are a few `apt` tasks
that need modifying to not use `ceph_stable_release_uca` unless
`ceph_origin` is `repository` and `ceph_repository` is `uca`.

When using monitor_address_block or radosgw_address_block variables
to configure the mon/rgw address we're getting the first ip address

When there's VIP on that network the first filter could return the

This seems to affect only IPv6 setup because the VIP addresses are
added to the ansible facts at the beginning of the list. This is the
opposite (at the end) when using IPv4.
This causes the mon/rgw processes to bind on the VIP address.
