[WFLY-410] Custom stack resource for JGroups

[rachmatowicz]

This PR does the following:

• implements a custom Stack resource for the JGroups subsystem which maintains protocol order by returning SortedSets of children instead of Sets
• this obviates the need for a separate PROTOCOLS attribute to maintain order as in legacy versions

Missing copyright header.

[rachmatowicz]

Done.

I think this will break in a managed domain because when a slave HC registers it gets shipped the domain config from the master as a List and then the slave HC converts those into Resources. And a standard Resource impl is used, so your custom resource will be lost.

The slave HC uses custom Resource impls it knows about, but it has no way to know about subsystem resource impls.

This is a general issue with domain mode that I hope to address in the next week or so. A fix is needed for the blocker RBAC feature so it has to happen. So I prefer to hold off on merging this until that's in.

Sorry for not thinking of this before.

[rachmatowicz]

No problem on the delay. I have more custom resources besides this one :-)

[rachmatowicz]

This PR has been languishing for 3 months ... can we get it merged?

[bstansberry]

I have to write the thing to let it work in a managed domain. :(

I'm still stuck in EAP 6.2 mode.

[rachmatowicz]

Argh! My fault - I now see the comment above which I remember reading but just forgot about!

[bstansberry]

Nah; I wanted to get that done a long time ago. Unfortunately the easy solution I had in mind was bogus so now I need to do it properly.

[bstansberry]

Closing this, as Paul went another way with #6992. Sorry it's taken so long to get the domain mode thing that was blocking this done.
