What's changed and what's your intention?
This PR adds an HTTP API for CPU profiling. It also refactors the mem prof handler to make chaining handlers to the router easier.
Sample at 99 Hertz, for 5 seconds, output report in protobuf format.
Sample at 99 Hertz, for 60 seconds, output report in flamegraph format.
Sample at 49 Hertz, for 10 seconds, output report in text format.
This feature is disabled by default. To enable it, we need to build the binary with
pproffeatureBecause the pprof API needs to sample for a specific duration, we must apply the timeout layer before it.
Note that this might panic on Apple silicon chips (M1/M2)
This PR also closes the test region in TestBase which should fix the test case
