Emacs CI

[Fermin]

Hello everyone!

    Great!, seems like we have a mail list, awesome.

    I saw briefly the work of Toon in the emba pipeline, also awesome work!

    I didn't had too much time (I have tests to fail!) but I'm thinking of merge the
    parallelization of the test with the current pipeline.

    We can discuss maybe the organization of the tests, I have a few question about this:

•     It makes sense to just launch the test of the package that has been change?
•     To launch all the (expensive)tests, how its the best way to group them? I did it alphabetically,but probably there is a better way to improve the usage of 2 runners.

     Interesting strategy the way that the Emacs image is push into the repository, in my case, I just add to the cache the Emacs binary but work with the same base image,
    probably the actual strategy is faster.

Regards,

Fermin
