this commit introduces the ability to use fqdn for mon/mds name while

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.
0644 should never be a directory mode. 1777 makes it so that any user
can create a ceph client, not just root. (This is helpful if, for
instance, nova-compute is running as non-root.)
If using another method to generate a consistent fsid, then we can
skip creation of an (unused) cluster UUID file. If cephx is disabled
as well, we can skip creation of the fetch directory entirely.
The firewall checks can fail for any number of reasons -- e.g., the
ceph cluster hostnames are unresolvable from the ansible host, or the
ports are filtered by some intermediate hop, etc. Make two changes to
make those checks better:
* Set pipefail when running the checks, so if nmap itself fails the
command will be marked as 'failed'. Specifically, this fixes the
case where the hostnames cannot be resolved.
* Add a new variable, check_firewall, which can be used to disable
checks entirely. Specifically, this fixes the case where some
intermediate firewall filters the ports, so nmap returns "filtered".
Installs on RHEL with ceph_origin set to distro previously would fail
because no packages would get installed, but all of the checks passed
fine. This adds support for ceph_origin: distro, simply installing the
packages using yum/dnf and assuming that the sysadmin has provided a
repository containing them.
This also supports the use case where Satellite or a similar local
mirror is in use, and the admin does not or cannot use the additional
repositories the role would otherwise add.
In our use case we might only be configuring mons and not osds in the
same call, so we don't want to check variables needed for osds when they
are not needed to configure a mon.

Currently deploying a MON fails with "bad symbolic permission for mode"
errors due to the file/directory modes not being interpreted as octal
values. This commit updates roles/ceph-common/tasks/main.yml to set
the file/directory modes to strings so they can be interpreted
correctly.
Closes issue #525
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.
We have a requirement to install the packages first without
configuration. These tags should allow us to target the tasks need to do
that.

Currently, all the ceph package installation resources use
"state=latest", which means subsequent runs of the ceph playbooks
could result in ceph being upgraded if there are package updates
available in the selected repo.
This commit adds a new variable to ceph-common called
'upgrade_ceph_packages' which defaults to False. This variable is used
in the package installation resources for ceph packages to determine if
the resource should use "state=present" or "state=latest". If the
variable gets set to True, "state=latest" will be used.
Additionally, we update rolling_update.yml to override
upgrade_ceph_packages to true to permit package upgrades in this
context specifically.
Closes issue #506
It seems that in ansible 2.0 even if a task is skipped by it's `when`
clause not evaluating to true the variables in the play are still
rendered. Because these were not defined in defaults/main.yml ansible
was failing in installs/install_on_redhat where those variables are
being used in a `with_items` stanza.

Thanks to @cloudnull great patch at

we now have the ability to add more configuration options instead of
having to push a PR to add a new option to the template. So you can
dynamically add and remove flags.

It should be used to disable health warnings about number of PGs
being too low if some pools have very few objects bringing down
the average number of objects per pool. This happens when running RadosGW.
The default is 10 and since the warnings only occur with some use cases,
the default here is 10 as well. Set to 20 or more to silence the warnings.
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
When multiple monitor hosts attempt to create the fetch directory there
is the potential for the task to fail with:
"OSError: [Errno 17] File exists: 'fetch'"
This appear to be an issue with the file module trying to create the
same directory at the same time when the tasks has been delegated to a
single host.
This commit enables run_once on the affected task which should address
the issue.
This is a rare case but it happens. Since we're just calling
`monitor_interface` and not `hostvars[host]['monitor_interface'],
an error may occur when the current host's interface does not
exist on the other hosts. (eg. eth0 exists for node0, but it does
not exist on node1 and node2)
Fix for this is to use hostvars[host]['monitor_interface']
Fix back the rolling update playbook.
However every single time the playbook will run it will check for new
packages and install the latest ones. I don't think this is always the
desired behaviour. We need to find a way to conciliate both...
