Ceph

To get a specific value for a setting in a pool a user is required to run something like:

sudo ceph osd pool get $poolname $key

Where `$key` is one of:

crash_replay_interval|pg_num|pgp_num|
 crush_ruleset|hit_set_type|hit_set_
 period|hit_set_count|hit_set_fpp|auid|
 target_max_objects|target_max_bytes|
 cache_target_dirty_ratio|cache_target_
 full_ratio|cache_min_flush_age|cache_
 min_evict_age|erasure_code_profile|min_
 read_recency_for_promote

But there is no way to get all of the values for a given pool from that subcommand. Instead, a user is required to run an `osd dump`
that will contain a fairly verbose output of a lot of values that may not be interesting when only looking for the given pool:

In this case, I needed to get values for the 'data' pool:

$ sudo ceph osd dump

It would be ideal to be able to do something like:

$ sudo ceph osd pool get all $poolname

or maybe

$ sudo ceph osd pool get $poolname all
$ sudo ceph osd pool get $poolname *
