[WFLY-490] create a fake Caller in some tests
[WFLY-1790] fixed the HostScopedRole* operations
[WFLY-490] Update the current management model to JMX integration to hide the entire management model representation if access is prevented.

(Previously errors were being reported to the client and remaining functionality of JMX clients such as jconsole was subsequently broken)
[WFLY-490] Change role/[in|ex]cludes to role/[in|ex]clude
[WFLY-490] / [WFLY-1800] Upgrade to Remoting JMX 2.0.0.Beta2
[WFLY-490] / [WFLY-1804] Ensure the Subject of the current remote user is associated with the AccessControlContext for JMX requests.
[WFLT-490] / [WFLY-1618] Update the runtime role updates to avoid synchronization during boot.
[WFLY-490] / [WFLY-1618] Add TRACE logging to role mapping logic.

Generally this should not be required but in an extreme case of trying to identify why a user was or was not granted a role this can be used to identify the matches used in the decision process.
[WFLY-490] For IN-VM calls or more specifically calls that do not have a remote user associated with the AccessControlContext use a SecurityManager permission check to verify the calling code can run as the default role.
