Also report python version, collect supported from pypi, and report where appropriate

For user: it might be valuable to know that newer version drops support for the python he uses, and what would be the latest newer (if any) which supports user's python

For developers: would be useful to know % of users at this point in time who still uses the version they are considering to drop. Would have been very valuable e.g. in python 2 to 3 migration times.

i know that the access logs of the backend server encodes the CI info. i need to check if the CI info is stored in database. also i would want to restrict i think the amount of information going into the db, and what aspects of it are accessible/searchable. this will require a joint refactor of both client and server.

i meant to say the same mechanism we are using for CI can be used for other pieces. and since my intent was not to make scope of etelemetry service beyond our projects, we can craft some aspects specific to our needs.

I thought that ultimately it was intended to be generic, thus not only for our projects - I don't think they are too special anyways to require some special treatments.
