WIP: Disable http client metrics, they bloat metrics

[lolepezy]

It creates new tag value for every new snapshot URL so it bloating metrics

http_client_requests_seconds_max{client_name="rrdp.ripe.net",error="none",exception="none",method="GET",outcome="SUCCESS",status="200",uri="/f351ea8a-62f5-4138-ad36-e93aa102fa88/39483/snapshot-ffd032beb276ee833af3ce693f506bbbc7b57dac71b946964dad8f27612baa57.xml",} 0.0

So I replaced it with a manual gauge

I think rpki monitoring has a neat solution for this, think it is a spring bean though. We can still have the metrics but not have the url as "low cardinality metric"
