This ticket is to decom bast3001 after it has been replaced by bast3002 in parent task T156506.
I say "decom" instead of reclaim because the reason to replace it was broken disk and it's very old.
[x] - all system services confirmed offline from production use
[x] - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place.
[x] - remove system from all lvs/pybal active configuration
[x] - any service group puppet/hiera/dsh config removed
[x] - remove site.pp (replace with role::spare if system isn't shut down immediately during this process.)
START NON-INTERRUPPTABLE STEPS
[x] - disable puppet on host
[x] - remove all remaining puppet references (include role::spare)
[x] - power down host
[x] - disable switch port
[x] - switch port assignment noted on this task (for later removal)
[x] - remove production dns entries
[x] - puppet node clean, puppet node deactivate, salt key removed
END NON-INTERRUPPTABLE STEPS
[x] close T154603 (as invalid or rejected?)
 - system disks wiped (by onsite)
 - system unracked and decommissioned (by onsite), update racktables with result
 - switch port configration removed from switch once system is unracked..
