Add enable/disable log query functionality (#2294)

* Add enable/disable log query functionality

This change adds the ability for server owners to allow log querying
from inside the client.  In the event the functionality is not allowed a
result is returned indicating the functionality is disabled.

* Added translation

Added the ability for the disabled messages to be translated.
