WFLY-4105 Add support for explicit fork channel protocols

https://issues.jboss.org/browse/WFLY-4105
Explicit fork channels can augment the parent channel by adding protocols to their fork stack.

Introduces a number of consequential and tangential changes:
* Shares runtime protocol resource registration logic for use with fork stack
* Eliminates read-only PROTOCOLS attribute of the stack resource, protocol order is implied by ModelNode.asPropertyList()
* Deprecates custom add-protocol/remove-protocol operations of stack in favor of standard add/remove protocol resource operations
* Deprecates "extended" stack/transport/protocol add operation parameters
* Normalizes transport address to match protocol address (e.g. transport=UDP instead of transport=TRANSPORT).  Redundant TYPE attribute is now deprecated.
* JGroups subsystem now uses generic describe handler
* Eliminate redundant custom read-attribute and write-attribute handlers for cache and cache-container resources
