amslvs1-4 have been decom'ed in the parent task as in "removed from puppet, icinga, dsh, DNS (except mgmt) etc" and shutdown
i'm expecting they will not be reused for something else, but i'm not 100% sure because racktables doesn't have data about warranty and purchase date
this ticket is for the follow-up work to:
- disable switch ports
- wipe disks
- unrack physically
- update racktables/servermon
- remove mgmt entries
- recycle hardware
