[pve-devel] [PATCH v2 storage] CephConfig: ensure newline in $secret and $cephfs_secret parameter

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

Ensure that the user provided $secret ends in a newline. Otherwise we
will have Input/output errors from rados_connect.

For consistency and possible future proofing, also add a newline to
CephFS secrets.

changes:
- instead conditional with regex, use chomp and always adding the newline
- do the same to $cephfs_secret

From previous version (though not sure if they still apply with these
changes):
