defaults: add ceph related vars file This is to add a granularity level. We can have ceph specific variables that user shouldn't have to change here.

Set the default crush rule in ceph.conf Currently the default crush rule value is added to the ceph config on the mon nodes as an extra configuration applied after the template generation via the ansible ini module. This implies two behaviors: 1/ On each ceph-ansible run, the ceph.conf will be regenerated via ceph-config+template and then ceph-mon+ini_file. This leads to a non necessary daemons restart. 2/ When other ceph daemons are collocated on the monitor nodes (like mgr or rgw), the default crush rule value will be erased by the ceph.conf template (mon -> mgr -> rgw). This patch adds the osd_pool_default_crush_rule config to the ceph template and only for the monitor nodes (like crush_rules.yml). The default crush rule id is read (if exist) from the current ceph configuration. The default configuration is -1 (ceph default).
