Disable/exclude metrics buckets

[gilliardmacedo]

From labbsr0x/servlet-monitor#31

Only more advanced users of Prometheus metrics really uses buckets/histograms. By removing metrics buckets, we will reduce in over 60% the amount of processing and byte output in our metrics endpoint with no loss in quality.

Currently we have something like this for each metrics/label combination:

request_seconds_bucket 1
request_seconds_bucket 2
request_seconds_bucket 3
request_seconds_bucket 4
request_seconds_bucket +inf
request_seconds_sum
request_seconds_count
response_size_bytes

By removing buckets, we would reduce to something like

request_seconds_sum
request_seconds_count
response_size_bytes

Proposal

• Buckets metrics made optional for request_seconds and dependency_request_seconds
• Disable buckets output by default (will only generate _sum and _count metrics for each request)
• Only enable buckets if configured explicitly using existing param "buckets" with values like "0.1,0.3,2,10" for example

@flaviostutz @gilliardmacedo makes sense to me. Sorry for such a late response (not really having time to open source as of now)
