[pve-devel] [PATCH v3 manager 2/3] fix #2515: ui: ceph pool create: use configured defaults for size and min_size

[Aaron Lauterer <a.lauterer@proxmox.com>]

Instead of hard coded defaults for the size and min_size parameter,
check if we have defaults configured in the ceph.conf or config db and
use those.

There are clusters where different defaults are needed. For example if
the cluster spans two rooms and needs to survive the loss of one. A
size/min_size of 4/2 are common defaults in such a situation.

changes since
v2:
* default 3/2 values for size/min_size are now set right when we get the
  API response. The component expects to get a value set via cbind.
  This avoids setting default values in multiple places within the
  component.

v1:
* set defaultSize and defaultMinSize to undefined in CephPoolInputPanel
* set them in cbindData in PoolEdit (needed when editing existing pool)
* waitMsgTarget when opening pool create window
* guard returned values for config keys in case they are empty
