prometheus mds metrics no longer available

# Issue report

Somewhere between revision 1100 and 1139, some prometheus metrics went missing. The one I've noticed so far is the MDS metrics. I found this issue when one of my clusters stopped reporting those metrics. Seeing it was on a newer version, I upgraded the working clusters to the latest revision and they are now all exhibiting the same issue.

## What version of MicroCeph are you using ?

microceph (reef/stable) 18.2.4+snapc9f2b08f92

## What are the steps to reproduce this issue ?

1. Install latest reef/stable release.
2. Enable prometheus mgr module: `ceph mgr module enable prometheus`
3. Curl endpoint to get metrics and check for mds metrics: `curl localhost:9283/metrics| grep mds`

## What happens (observed behaviour) ?

Only the metadata of the MDS daemon is there:
```
# HELP ceph_mds_metadata MDS Metadata
# TYPE ceph_mds_metadata untyped
ceph_mds_metadata{ceph_daemon="mds.scooby",fs_id="1",hostname="scooby",public_addr="10.0.0.7:6809/1914232058",rank="0",ceph_version="ceph version 18.2.4 (e7ad5345525c7aa95470c26863873b581076945d) reef (stable)"} 1.0
```

## What were you expecting to happen ?

Before 1100 -> 1139 upgrade, all MDS metrics were available:
