[pve-devel] [PATCH manager 2/2] fix#5570 ui: ceph: make MDS ID configurable

[Aaron Lauterer]

Since the ID of an MDS cannot start with a number [0], we cannot just
use the hostname in all situations, as they are allowed to start with a
number.

By having an extra field for the MDS ID, we can check for that via a
regex. This field is filled with the hostname when the host on which it
should be installed is selected.

This means, we can remove the extra ID field, as additional MDS, and
their unique ID can be set with the new ID field.
