Support collector service instrumentation

[wu-sheng]

In order to help the collector performance test, I add a collector agent.

• Instrument all collector service.
• Collect metrics: success rate, calls and avg response time
• Output all metrics to log in Warn level

FYI @ascrutae , collector startup script need an argument (named -instrument) to make this agent works.

LGTM
