Bug 1754638: loopback: don't tear down

[squeed]

There is a bug in CRIO that issues deletes against processes running in the root network namespace. This means we take the node's loopback interface down. This is bad.

This bug was always present, BTW, but we skipped loopback on teardown.

I think this has to be 4.3 then backported to 4.2.z now..

[squeed]

this is a critical bug - we definitely need this in 4.2.0

For the record: Xiaoli said on a 6am call today that if we had fixes in for this bug by EOD today, QE could absorb it.

• expected dependent Bugzilla bug 1754154 to be in one of the following states: VERIFIED, RELEASE_PENDING, CLOSED (ERRATA), but it is ASSIGNED instead

Comment /bugzilla refresh to re-evaluate validity if changes to the Bugzilla bug are made, or edit the title of this pull request to link to a different bug.

I am approving this for 4.2.0. Since we cannot merge to 4.3 yet I am not waiting on the parent BZ to be VERIFIED. Since I want this in 4.2.0 and not 4.2.z I'm ignoring the complain about that as well.

Now hopefully CI passes.
