Replace stdlib dependencies by third parties (requests, click)

[almet]

We currently use overlapping projects in different parts of the code (for instance click and argparse). The reason why we use these different projects was to be able to use the scripts without having to install dependencies.

After a discussion, we believe it would be good for the project to decide on one set of tools instead, as it would provide an uniform tooling, be better in terms of tracking dependencies, and ultimately because some options seem simpler than their counterparts.

We want to ensure our build scripts are working well with this change, and so should try to use poetry run python rather than just python in our CI.

Note

This is related to #946 but the two issues are actually separated, as it's possible to fix one without the other.
