commit 7146571b702579fa1367598ab278ca2f8ec1e156

    Adds alarm time constraint support to ceilometer CLI

    Time constraints can be specified for create and update
    families of commands with the following format:

    --time-constraint name=constraint1;start='0 11 * * *';duration=300

    This switch can be specified multiple times in the case of
    multiple time constraints.

    With update commands, time constraints are updated by name,
    e.g. --time-constraint name=constraint1;duration=500 updates
    the constraint 'constraint1' with a new duration 500.

    Time constraints can be removed with update commands using the
    switch --remove-time-constraint=constraint1,constraint2 .

    Example of display outputs:
