kraft.yaml: Use stable version for all components

[razvand]

This has the benefit of not requiring updates whenever there is a new version release of Unikraft components.

Hello, @razvand. I've tested the changes on my system and here is what I have noticed:

Firstly, app-python3 uses functions from posix-event(/home/X/apps/app-python3/build/libpython3/origin/Python-3.7.4/Modules/timemodule.c:1843: undefined reference to select), so we need to add - CONFIG_LIBPOSIX_EVENT=y to the kraft.yaml file.

Secondly, the app doesn't seem to work on the stable branch of Unikraft. This due to issue unikraft/unikraft#529, which is fixed by commit unikraft/unikraft@9bf6e63 found only on the staging branch.

Apart from that, everything seems fine to me.

This lib-python3 PR needs to be integrated first. Use that. It will fix things.

Ah, damn. Please see if changing stable to 9bf6e63 fixes it. Or, if not, using staging. I will then update kraft.yaml accordingly. Then we'll make a note for future update of kraft.yaml to stable.

Oops, didn't see that PR. Yes, makes sense now.

Yes, simply changing the version to staging(or 9bf6e63) seems to do the job.

All good now. Thanks, @razvand!

Tagging the core version to a commit is a temporary solution that will work for now but it is a bit ugly. In the future all app-* repos will have the version attributed to the corresponding library (and not the Unikraft internal version).

Approving for now until this migration occurs, thanks.
