in order to have a build on the galaxy we need to have a proper
dependency set for ceph-common. On the galaxy ceph-common does not
exist, only ceph.ceph-common is available.

This adds a script, generate_group_vars_sample.sh, that generates
group_vars/*.sample from roles/ceph-*/defaults/main.yml to avoid
discrepancies between the sets of files. It also converts the line
endings in the various main.yml from DOS to Unix, since generating the
samples was spreading the line ending plague around to more files.

Skip keyring tasks when cephx is disabled

Previously, creating pools was skipped if cephx was disabled; instead,
we should only skip key creation if cephx is disabled, and create
pools any time openstack_config is true.

Skip a number of ceph keyring-related tasks (or remove the keyring
portion of some tasks) when cephx is disabled. Specifically, avoid
generating the initial keyring, which only clutters up the ansible
repo if cephx is not in use.

If cephx is set to false, the "set keys permissions" task fails with:

file ({# ceph_keys.stdout_lines #}) is absent, cannot continue

This skips that step when cephx is false.

run containerized daemons in virtual machines.
to enable it simply do:

Refact code using `set_fact` to handle 'legacy' versions

At the moment, all the tasks using the file module are duplicated to have differents ownerships depending on the fact `is_ceph_infernalis`.
The goal of this commit is to have a new logic for this:
- First set facts depending on the `is_ceph_infernalis` fact
- Create the files or directories using the setted facts as ownerships.

to avoid warning from ansible v2. works for both `1.9.4` and `2.0.0.2`.

fixes ceph_stable_release logic mentioned in issue #446

rework the various `when' tests to use that array.

I changed the argument used for starting the mds server. (pre
infernalis)
```
service ceph start mds
```
errors, while
```
service ceph start mds.$hostname
```
correctly starts the service.

I changed the mds directory ownership from ceph:cephh to root:root
again, for pre-infernalis.

And finally, add the ceph_stable_releases checks for the upstart
activation task `for or after infernalis release'.

I have seen a number of failures on this task due to mismatch of
checksum of source file and destination.  I suspect this is due to a
race condition caused by several hosts simultaneously copying the same
file to single location on the deployment server.

This change simply updates the 'copy keys to the ansible server' task
by adding 'run_once', which limits the task to being run on a single
MON host.

* without this, the handler in ceph-common that depends on
  the value of 'mon_group_name' would fail

Since we renamed the variables and removed the old 'docker' variable we
can now collocate container daemons with standard bare metal deployment.
For instance, monitors can be containerized but osds can be deployed
traditionally.

Currently, the fetch directory is created in your working directory
(where ansible is run from).  We prefer to not keep any state in this
directory and would prefer to have the fetch directory configurable so
we can store it outside of our code checkout.

This commit creates a new variable in each role called
`fetch_directory` (defaulting to the previous value of 'fetch/'), and
then updates each reference to 'fetch' to use the new variable instead.

Closes issue #383

Allow configurable pg_num for OpenStack pools

This commit updates the ceph-mon role to allow the pg_num for each pool
