CLOUDSTACK-2522: While processing agents behind on ping, we may fail to process a host that
is already in 'Down' state

Changes:
- Added a transition for DOWN -> DOWN state on PING TIMEOUT so that transition will set
mgmt_server_id in the host table to null.

> From the code I see that there is no transition for hosts from DOWN state with event
PING
> timeout. This causes an error when AgentMonitor does a delayed processing of the ping,
for a host that has gone to DOWN  state. As a result the host state never gets updated in
our DB.
> Only when host state transition happens then is the mgmt_server_id made null by
> HostDaoImpl:: Update code.
> Since state transition never happens, mgmt_server_id remains non-null causing
> reconnect of this host not to trigger.
> I think this can be fixed by introducing state transition for DOWN state on
> ping timeout.
