Diff: https://reviews.apache.org/r/71993/diff/4/

Testing (updated)

Validated metrics which are getting generated at configured interval when usersync and tagsync
services start. 
I have kept below parameter configurable
1. Metrics Name (Default value metrics.json)
2. Metrics Directory (must have write permission and default value /tmp/)
3. frequency at metrics get updated (default value: 10 sec)
4. metrics enabled or disabled 
Checked for metrics.json being regularly updated based on JVM resources utilization. Validated
for usersync as well as tagsync process.
