Remove openstack-101 from accessbot
Remove openstack-101 from accessbot

In discussions at the last PTG[1] and in subsequent First Contact
SIG meetings[2] we've decided that the #openstack-101 channel
should be removed and rolled into the #openstack-dev channel.

Why? Good qustion:
 - No one is good at sitting in and watching the #openstack-101
   channel outside of OUI training periods.
 - It would be better for new contributors to ask questions in
   a channel that people with the answers already activly monitor.
 - 101 is an American-ism, that not everyone in the world would
   understand.

This means that during OUI trainings there will be more noise in
openstack-dev. However, trainings mostly happen the weekend
before a summit, so at a very quiet time. And would mean trainees
would already have practice and now where to come for questions.

There is another patch[3] which will remove openstack-101 from
the status and meet bots.

Finally, as per renaming instructions[4], once these patches
land, a redirect will need to be created, the topic updated and
current residents of the channel will need to be informed to
relocate.
