Validation done on xenial and bionic

This log is part of the test I did to check --extrausers can be used to add and del users.

Thank you for taking the time to verify this stable release fix. We have noticed that you have used the verification-done tag for marking the bug as verified and would like to point out that due to a recent change in SRU bug verification policy fixes now have to be marked with per-release tags (i.e. verification-done-$RELEASE). Please remove the verification-done tag and add one for the release you have tested the package in. Thank you!

@mvo This fix raised bionic-update's shadow version above cosmic's. Do you plan fixing that or just wait for Cosmic's EOL?

I inspected snapd and noticed that we don't invoke "userdel" or "deluser" in any production code. We have some tests that do use it and we now support --extrausers there.

I'm inclined to mark the snappy task as fix released, given that we inherit the relevant tools from core and core18 snaps which in turn are fed with updates from the archive. While in the past we carried this patch locally in a package override, given that it is now fixed in both Xenial and Bionic I cannot imagine anything else we'd have to do in the context of this issue.

With this rationale I'm marking it as fix released. Please reopen if there's more relevant work to be done.

Big thanks guys!
