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.
This commit allows you to set a new variable to 'true' if you want to
have ceph admin key copied over different kind of hosts such as MDS,
OSD, RGW. To enable this just set `copy_admin_key` to true.
Closes: #555

When autodiscovering disks, disks can be skipped if either they are
removable, or if they have partitions on them. Skipped actions have no
'rc' attribute, though, so the 'ceph prepare' conditional fails unless
we first check to ensure that the results were not skipped before
checking the return value.
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".
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.
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.
The playbook uses the ceph-fetch-keys role to connect to the mons and
retrieve keys for the OSD bootstrapping. Ensure that all your mons for
the cluster you're adding the OSD to is in your inventory in the mons
group. This ensures that a proper ceph.conf is created for the new OSD.

The purpose of this is so we can connect to the mons and gather the keys
needed to configure an OSD or additonal MON without having to reconfigure
the existing mons at the same time.

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.

Mainly because some packages are still not there for upstream which will cause
it to break installs that would otherwise would succeed
