install prisma migration files - connects litellm proxy to litellm's prisma migration files (#9637)

* build(README.md): initial commit adding a separate folder for additional proxy files. Meant to reduce size of core package

* build(litellm-proxy-extras/): new pip package for storing migration files

allows litellm proxy to use migration files, without adding them to core repo

* build(litellm-proxy-extras/): cleanup pyproject.toml

* build: move prisma migration files inside new proxy extras package

* build(run_migration.py): update script to write to correct folder

* build(proxy_cli.py): load in migration files from litellm-proxy-extras

Closes https://github.com/BerriAI/litellm/issues/9558

* build: add MIT license to litellm-proxy-extras

* test: update test

* fix: fix schema

* bump: version 0.1.0 → 0.1.1

* build(publish-proxy-extras.sh): add script for publishing new proxy-extras version

* build(liccheck.ini): add litellm-proxy-extras to authorized packages

* fix(litellm-proxy-extras/utils.py): move prisma migrate logic inside extra proxy pkg

easier since migrations folder already there

* build(pre-commit-config.yaml): add litellm_proxy_extras to ci tests

* docs(config_settings.md): document new env var

* build(pyproject.toml): bump relevant files when litellm-proxy-extras version changed

* build(pre-commit-config.yaml): run poetry check on litellm-proxy-extras as well
