Hello people, really hope you're all doing fine.
Really hope everything is okay, families, health, new year celebration, ...

The following is an attempt to finish my work on https://www.cubicweb.org/ticket/17254012
I was supposed to modify Cubicweb, and use pkg_resources to retrieve cube's version.

Everything seems to work nice,
but I'm not sure this solution is clean enough:
- because of the nested try/except blocks
- because of me passing sys.path[0] to a function
- because this hack is written only to handle some cubes used during migration tests

During the migration tests, there are some cubes that are in the old format.
pkg_resources was not able to "find ditributions" related to those cubes.

I've done, what Philippe advised to do: build eggs for those cubes.
And to find those "not pip installed distributions",
I've used the pkg_resources.find_distributions function.

Thanks a lot for your advices and suggestions.
Best wishes for 0x7e4
