Add `SELF_LOGS_PATH` env variable to allow setting different tool's log location & python 3.12 fixes

[sashasimkin]

Main reason for this change is that I'm trying to run this script in lambda as --one-time, and in that environment only /tmp/* is writable.

Also, I've updated pyyaml and introduced patching for yschema library to make it compatible with python 3.12.
