The ceph status command returns a lot of information stored in variables
and/or facts which could consume resources for nothing.
When checking the quorum status, we're only using the quorum_names
structure in the ceph status output.
To optimize this, we could use the ceph quorum_status command which contains
the same needed information.
This command returns less information.

Otherwise this will generate an ansible warning about the missing
filter.
[DEPRECATION WARNING]: evaluating xxx as a bare variable, this behaviour
will go away and you might need to add |bool to the expression in the
future.
Also see CONDITIONAL_BARE_VARS configuration toggle.. This feature will
be removed in version 2.12.

The role contains all the handlers for Ceph services. We decided to
leave ceph-defaults role with variables and a few facts only. This is
useful when organizing the site.yml files and also adding the known
variables to infrastructure-playbooks.
