Metrics: Report software versions for operator

[spuiuk]

It would be very useful to see the underlying software versions in the metrics page.

The software I am interested in are:

1. Samba version.
2. CTDB version (if in clustering mode).

@spuiuk What command should I issue to get the CTDB version?

[spuiuk]

For ctdb specifically we can use the ctdb version command.

However maybe we should just rely on rpm commands - so something similar to rpm -q ctdb samba python3 ?

[spuiuk]

also sambacc when we ship it as rpm.

[synarete]

Cool -- using rpm -q is the simplest solution. Thanks.

ctdb had a separate version only in the very beginning. since ctdb code was merged into the samba git repo a long time go, the ctdb version is just the samba version. I don't even remember whether ctdb reports its own version any more ..., @synarete , @spuiuk

should this be an issue in the smbmetrics project? @spuiuk , @synarete

Both of those values are already reported via labels on smb_metrics_status metric
