Testing
-------

ChangLog:

v3:
  - Move the couting out of common code path to http endpoint and master accept 
call separately to reflect its logic.

v2:
  - Documenting those metrics
  - Add test code for MetricsTest as suggested by Guangya
  - post-review.py does not update original 
RR(https://reviews.apache.org/r/44058/), but only create a new one even if I 
rebased.


Tests:
1. make check GTEST_FILTER="MetricsTest.Master" on Centos-7 
(3.10.0-123.el7.x86_640)

[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from MetricsTest
[ RUN      ] MetricsTest.Master
[       OK ] MetricsTest.Master (211 ms)
[----------] 1 test from MetricsTest (211 ms total)

[----------] Global test environment tear-down
[==========] 1 test from 1 test case ran. (244 ms total)
[  PASSED  ] 1 test

2. Verify its functionality with 'reserve' http endpoint as an test case

# curl http://ipdc02-kvm-guest2:5050/metrics/snapshot | python -mjson.tool | 
grep reserve
    "master/messages_reserve_resource": 0.0,
    "master/messages_unreserve_resource": 0.0,


# curl -i -d slaveId=6250553a-2f39-4a92-9073-4618d130f433-S1  -d resources='[ { 
"name": "cpus", "type": "SCALAR","scalar": { "value": 1 
},"reservation":{"principal": "XiaoHaHa"}}  ]' -X POST  
ipdc02-kvm-guest2:5050/master/reserve
HTTP/1.1 200 OK
