Modified (pre_)generate_ceph_cmd to make it usable with any command with
the same parameters as the ceph command

When creating a new pool, target_size_ratio was ignored by ansible module ceph_pool.py.
target_size_ratio is now used when pg_autoscale_mode is on.
Tests added to library tests.
This adds too the use in the role ceph-rgw.
