Log Message: ----------- add support for "decactivating" metrics_cache

Deactivating metrics_cache results in data *not* being pulled from it. This applies to both past and current data. Once a specified time has been reached, it is reactived and we start pulling from metrics_cache again. This logic is necessary for two purrposes. First, we need it simplify and speed up the data migration that will be necessary when upgrading to RHQ 4.11. Secondly, it is necessary for the resizing of cache partitions to take effect. For example, suppose we store data for up to 5 schedules per cache partition. We decide to store data for 10 schedules per partition. We need to deactivate the cache while the change takes effect.
