   ### Description
   
   We discovered this issue in one of our envs where a VM was running on the 
host but the state of the VM in the host was Stopped. Ideally power reports 
should have fixed this, but it didn't.
   
   This PR adds additional checks to ensure that when:
   * VM is in stopped state and power report is powerOn
   * VM is in running state and power report is powerOff
   It sends an update (publishes a message on Topic `VM_POWER_STATE`). The 
subscriber on this topic transits the VM as per the state & powerstate.
   <!--- Describe your changes in DETAIL - And how has behaviour functionally 
changed. -->
   
   <!-- For new features, provide link to FS, dev ML discussion etc. -->
   <!-- In case of bug fix, the expected and actual behaviours, steps to 
reproduce. -->
   
   I wasn't able to reproduce the issue. But updating the entry for vm_instance 
in the database helps.
   1. Launch a VM and ensure it's running.
   2. Run the below update query for the instance
   ```sql
   UPDATE vm_instance SET state = 'Stopped', power_state_update_count = 3 where 
id = 12345;
   ```
   
   It should switch back to 'Running' after next power state update, but it 
doesn't happen.
