Collector for working with data from the system profile

[mikle7771]

This implementation allows you to get metrics on slow queries.

mongodb_profile_slow_query_count{cl_id="58ffb6f25ee88911bb439499",cl_role="",database="admin",rs_state="2"} 1
mongodb_profile_slow_query_count{cl_id="58ffb6f25ee88911bb439499",cl_role="",database="config",rs_state="2"} 3
mongodb_profile_slow_query_count{cl_id="58ffb6f25ee88911bb439499",cl_role="",database="local",rs_state="2"} 0

--collector.profile-time-ts=30 Set time for scrape slow queries. This interval must be synchronized with the Prometheus scrape interval

For the collector to work, you must enable the profiler
