Subject: [PATCH] ui: cephfs: only allow CephFS creation if MDS is configured

Introduce the mdsCount again, I know remember again why I had it in
v3 of my CephFS series.. Use this to disable the CephFS create button
if we have no MDS configured, as this is a requirement.
Further change the gettext for 'No XY configure' to a format string
so that it can be reused.
