## Summary
A while ago we have added several notebooks to get users started training their own agents. These notebooks overlap in functionality with PrimAITE session but they are more suitable.
* removed primaite session
* removed any tests relying on primaite session (except some tests were converted into environment tests.
* removed any CLI commands that rely on `PrimaiteSession`
* Added deprecation warnings to any benchmarking code that will break now because they rely on the old Primaite 2 session. (I left the code in because when we update benchmarking to v3, this will be a useful starting point)
* added similar deprecation warnings to Session metadata writer, reader and transaction stuff, for the same reason.
* removed parts of the documentation that are no longer relevant (session, training config, policy)
* went through all existing yaml config files and removed training options (as they were for session only)
## Test process
Checked that existing pytests all pass, and updated some pytests to use environment instead of session.
