Code review comment for ~dannf/canonical-server-hwe-utils:tremont-post-move-test

According to this comment, which is my "user experience", https://warthogs.atlassian.net/browse/SHENG-1953?focusedCommentId=224561 and my knowledge[1], I would say this script is good enough to move forward. Polishing the output format and make a "smarter check" has lower priority.

[1] Pauli is the HMM of the chassis containing saenger and segers, and I have confirmed that saenger and segers are managed by our MAAS. I don't know how saenger and segers are racked exactly. However, once our MAAS could manage saenger and segers, we don't care how Pauli is setup.

lasell is owned and managed by IS according to this sheet of 18T move https://docs.google.com/spreadsheets/d/1Np7LUkv4KpuQOJCklL5NFGEs_8IwiEgbfL62PI99H0g/edit#gid=0 and lasell is not used in our setup now.
