Use Eventloop instead of direct EM code
Remove minitest stub monkey patch
Migrate XMPP specific topic logic
Remove dependency to patched stub method
Trying update patches to be consistent with protocol definition

Mostly to do with inform_type: inform_type shall be :creation_ok (not :created), :error (not
:failed), :creation_failed (not :failed) etc.
XMPP comm: subscribe shall yield topic object if success

If failed, yield XMPP error stanza
XML message: adding unimplemented each_ubound & each_bound methods
XMPP Topic: implemented on_message generic handler
