This is ready for review @allamand @tsahiduek could you review?

[csantanapr]

@niallthomson could you run an end2end test pipeline on this PR?

[csantanapr]

Minor nits, otherwise good to merge

[csantanapr]

Thank you so much @ybezsonov 🎉
I was able to test it and it works for me
@niallthomson please merge this when you have a chance

[niallthomson]

A great PR as usual @ybezsonov I have made 1 request for a change I feel is needed before I can merge.

That being said there are gaps with the ability to test this lab effectively, as the main commands that would validate whether this works or not are being skipped. Given the timeline we're looking to get this in I'd be fine as long as we agree this can be addressed as a follow-up.

[niallthomson]

Thanks for addressing those changes @ybezsonov This will be merged on Monday as the scope for our release tomorrow is locked.
