Stacked on #6252 — review that one first. This PR's diff is only the last two
commits; retarget to development/9.4 once #6252 merges.

Both quota gates in lib/utilities/monitoringHandler.js tested
config.isQuotaEnabled — the function reference rather than a call — so both
were always true, and all six quota metrics have always been registered.

Rather than calling the function, the conditionals are removed. Always
registering is what has actually happened since these checks were written,
nothing depends on the metrics disappearing when quota is off, and gating
registration would mean guarding every metric touch point against a metric that
was never created: crrCacheToProm reached bucketsWithQuota unguarded, and
the scuba wrapper observes its histogram in a finally block, on a path the
Veeam capacity route reaches with no quota gating at all.

Behaviour is unchanged — the six s3_cloudserver_quota_* series are exposed
exactly as before — so this is a dead code removal rather than a metric surface
change.

LGTM, but I think this warrants another set of eyes from product, to confirm we want/accept to have the metrics always (not just the presence of the metrics, but especially publishing actual data points for the bucketsWithQuota/accountsWithQuota metrics)

Comment thread lib/utilities/monitoringHandler.js Outdated
Both quota gates in monitoringHandler tested config.isQuotaEnabled -- the
function reference rather than a call -- so both were always true and all six
quota metrics were always registered.

Drop the conditionals rather than calling the function. Always registering is
what has actually happened since these checks were written, nothing depends on
the metrics disappearing when quota is off, and gating registration would mean
guarding every metric touch point against a metric that was never created:
crrCacheToProm reached bucketsWithQuota unguarded, and the scuba wrapper
