Initial updates to support preconditions

Any defined preconditions for a set speed event must be satisfied prior
to configuring the event parameters for fan control. These preconditions
will accept a list of group entries that include the value the group's
property must be to have the precondition met for that group. Once all
preconditions are met, the set speed event will be initialized and
become active.
