Support for action parameter constraints added to action service

An action parameter constraint provides a way to list the valid values that an action or action constraint parameter can take.  This
means more information about the action or action condition is available to the user of the action.
  
Currently there is only an implementation for enum parameter values, but this will be extended as the existing action implementations
are reviewed and value constraints are added as required.

The REST API can now be extended to provide this additional information.
