Review request for cloudstack, Abhinandan Prateek and Koushik Das.


New patch for master with fixed merge conflicts


Repository: cloudstack-git


Due to changes in underlying DAO layer to re throw exceptionsback to the caller DB HA functionality
is broken as MS is going down if master is down and salve is up. Fixed this by catching exceptions
in ClusterManagerImpl and take decision based on it.

Diffs (updated)

  framework/cluster/src/com/cloud/cluster/ c7c3710 



Testing is done in the following use cases
1. With db ha not enabled
2. with db ha enabled and
   - Shut down Master
   - Shut down slave
3. With db ha enabled
   - shut down 2nd db
   - shot down 1st db
4. with dbha enabled
   - shut down 1st db
   - up the 1st db
   - shut down 2nd db
   - shut down 1 st db
