trove needs a --force-delete option or allow to delete BUILD instances

[Matt Fischer]

For various reasons instances can get stuck in a BUILD state forever. When this happens the instances are undeleteable as the CLI won't let you remove instances in the BUILD state.

To fix this trove should add a --force-delete option like nova has or allow instances in BUILD to be deleted.

[Amrith Kumar (amrith)]

This should extend to cluster delete as well.

    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.
