Rename monitoring function Serve to Start
With the introduction of the Continuous Go Profiling,
the monitoring.Serve
function name loses its meaning,
as the goal of this function is no longer just setting
up a monitoring service endpoint,
but also starting a Profiler in a separate go routine.
This MR renames the function and deprecates the older version, logging a Deprecated message when still used.
