This commit removes all the documentation related to fedmsg and
github2fedmsg. Removes all the mentions of fedmsg when it makes sense or
change it to Fedora messaging.
I didn't updated
modules/releng_misc_guide/pages/sop_pushing_updates.adoc as this needs
somebody with the knowledge of the process to update it.

Since we are moving to matrix, lets drop reference to irc.
I may have missed a few of these and I left the Zodbot SOP alone for now
until we replace it with the new matrix one.
