Add performance metrics to lakeFSFS

[arielshaqed]

Add Hadoop metrics to lakeFSFS, and discover an easy way to view them in Spark and/or on DataBricks.

Measure at least these operations:

• Total time spent on each lakeFS API. Ideally find how to add context to it.
• ~Total time spent on each of {setup,commit,abort}{Job,Task}~
