After VAULT-20259 we did not enable the undo logs verification. This
reenables the check but modified to check the status of the primary and
follower nodes, as they should have different values.
While testing this I accidentally flubbed my version input and found the
diagnostic a bit confusing to read so I updated the error message on
version mismatch to be a bit easier to read.

When verifying the Vault version, in addition to verifying the CLI
version we also check that the `/sys/version-history` contains the
expected version.
As part of this we also fix a bug where when doing an in-place upgrade
with a Debian or Redhat package we also remove the self-managed
`vault.service` systemd unit to ensure that correctly start up using the
new version of Vault.
