[pve-devel] [PATCH manager v2 1/2] api: ceph: add applications of each pool to the lspool endpoint

[Stefan Sterz <s.sterz@proxmox.com>]

since ceph luminous (ceph 12) pools need to be associated with at
least one applicaton expose this information here too so that clients
of this endpoint can use that information

even though an application needs to be defined for a pool since
luminous, i tried to make this code fail gracefully in the case the
rados mon command fails or there is no application for a given pool.

thanks @ alwin antreich for pointing out that pools have applications!
