[pve-devel] [PATCH manager v3 1/2] api: ceph: add applications of each pool to the lspools 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 it
