decomission jabber server
the jabber server is not really used anymore, and we need the LDAP field for the new email service (in #30608 (moved)).
decommission the server (chamaemoly) with a warning period for users to have time to migrate their rosters off the server.
roadmap:
- T-30d (2019-09-16): warn users about impeding shutdown,
- T (2019-10-16): shutdown the jabber service itself (
service prosody stop
) - T+7d (2019-10-23): start the server decommissioning process
- remove from nagios
- "undefine" the VM
- queue disk destruction in another +7d
- remove from LDAP
- remove from DNS
- remove from Puppet
- remove from tor-passwords
- remove from documentation
- schedule backup cleanup (+30d?)
