Add "atest host rename".

In order to support rollback hosts in case hosts don't work afer
migration, add the "atest host rename" command.
"--for-migration" should be called after we migrate hosts from
staging/prod to skylab.
"--for-rollback" should be called after we rollback hosts in
skylab.

Do not migrate hosts with invalid hostnames.

When a host is migrated, it'll be renamed to host-migrated-do-not-use
in AFE DB. hosts with names ending with "-migrated-do-not-use" can't
be migrated to skylab. This was noticed in CL:*636668
