"Hard" Deconfigure Override

For overriding those subsystems that require "hard" deconfiguration (CPU and memory), the OBP commands asr-enable and asr-disable are used to selectively enable or disable each subsystem.

There are duplications between the soft and hard overrides. If possible, the hard override commands asr-enable and asr-disable should be used.

To keep track of the status of all manual overrides, a new user command, .asr, is provided to summarize the current settings.
