plugin: Guestful discover plugin about tmt HOT 2 OPEN

The current discover plugin is guestless, does that mean that this plugin is run on the host?

Correct, discovers tests e.g. in the fmf files in the local git repo.

The ExecutePlugin seems to be guestful

Correct, runs tests on a given guest.

Stinks like a dist-git & rpmbuild scenario again: run discover, run prepare, re-run discover because prepare changed the state of the world somehow. Complicated by the need to access prepare artifacts - the rpmbuild runs on the tmt runner, IIUIC? There's a pull from guest to runner, artifacts might be locally available after all. Re-running discover is in no solid shape though.

@lukaszachy looks familiar?

from tmt.

Painfully familiar. Time to make it generic then and figure out how multihost should work (respect discover phase's where? run it on first guest and copy tests everywhere? ...)

Maybe we can do more usable skeleton as part of #2784 (or at least put some future -ready parts there).

For now it looks that during prepare, after test are discovered, the install require/recommend has to be calculated again.
There are some common pieces - install tool, run it and let the discover happen.
