Support CRUD endpoints for Managed Files (#9924)

* fix(openai.py): ensure openai file object shows up on logs

* fix(managed_files.py): return unified file id as b64 str

allows retrieve file id to work as expected

* fix(managed_files.py): apply decoded file id transformation

* fix: add unit test for file id + decode logic

* fix: initial commit for litellm_proxy support with CRUD Endpoints

* fix(managed_files.py): support retrieve file operation

* fix(managed_files.py): support for DELETE endpoint for files

* fix(managed_files.py): retrieve file content support

supports retrieve file content api from openai

* fix: fix linting error

* test: update tests

* fix: fix linting error

* fix(files/main.py): pass litellm params to azure route

* test: fix test
