Rohit Yadav 5750e56be5 server: improve DB optimisation, indexing and reduce table scans ...

In this example commit, we look at:
- Adding missing indexes to speed up queries
- Reduce table scans by optimising sql query and using indexes
- Optimising sql queries to remove duplicate rows (use of distinct)
- Reduce CPU and DB load by using jprofiler to optimise both sql query
  and CPU hotspots

server: reduce CPU and DB load caused by systemvm ::isZoneReady()
For this case, the sql query was fetching large number of table scans
only to determine if zone has any available pool+host to launch
systemvms. Accodingly the code and sql queries along with indexes
optimisations were used to lower both DB scans and mgmt server CPU load.
