Add command to delete BUILD instances and clusters

Sometimes an instance/cluster can be stuck in BUILD state forever.
Attempting to delete the instance in this state is currently not
allowed. Add force-delete and reset-status command. Reset-status
will reset the status of an instance to ERROR and cluster to NONE.

The reset-status command can only be used if the instance/cluster
is in BUILD or ERROR state. Resetting the status of an instance in
ERROR state can be useful as an instance might go ACTIVE after the
specified timeout. Once the status has been reset it is possible
for an instance to go ACTIVE if it receives a hearbeat from the
guestagent.

Force-delete will combine functionality of reset-status and delete.
