New description:

 the jabber server is not really used anymore, and we need the LDAP field
 for the new email service (in #30608).

 decommission the server (chamaemoly) with a warning period for users to
 have time to migrate their rosters off the server.

 roadmap:

  1. T-30d (2019-09-16): warn users about impeding shutdown,
  2. T (2019-10-16): shutdown the jabber service itself (`service prosody
 stop`)
  3. 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?)
