Decommission buildbot masters

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

  • 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
