Decommission buildbot masters

There are a few steps that need to be followed here in order to decommission the master slaves.

• First the masters can be found on https://secure.pub.build.mozilla.org/slavealloc/ui/#masters

• In order to decommission you must:
  • Disable them from production
  • shutdown the masters to avoid having alerts on puppet
  • remove from puppet repository (hg.mozilla.org/build/puppet/)
    • manifests/moco-nodes.pp
  • remove from puppet sysadmin nagios alerts ( git-internal.mozilla.org/sysadmins/puppet.git)
    • modules/nagios4/manifests/prod/releng/scl3.pp
  • remove from tools repository (/hg.mozilla.org/build/tools)
    • buildfarm/maintenance/production-masters.json
  • delete masters from DB
  • Open bug to MOC: Service Requests for decommission
