Pipeline live debugging enabled as before (tmate)

[juditnovak]

With the old workflows it was very easy to debug worse issues with one's application (only appearing on the pipelines ;-) ) using Tmate.

However it's less convenient to do with the latest versions of the workflows.

Would it be possible to re-introduce this, truly important feature?

For history (copied from MM)—was waiting for Azure runners to implement full SSH access at any time during integration test jobs (so that UX is designed for full SSH access & GitHub runner UX is consistent), but Azure runners were stalled for a few months, so should implement UX for just GitHub/IS self-hosted runners

@carlcsaposs-canonical do not expect Azure runners the nearest time. The topic is outside of our control.

AFAIK, SSH access is possible nowadays for self-hosted runners. Can we use this approach?
What about to add optional upterm? It can be similar to the optional allure: true.

What do you think?
