Remove an unnecessary dependency and make a function visible to mypy.

[mikolajz]

Title

Remove dependency on importlib_metadata (even on Python 3.8 stdlib works) and make completion_cost visible to mypy.

Relevant issues

The extra dependency was causing an issue due to another library with lots of strict dependencies. I also had a mypy error in my code.

[REQUIRED] Testing - Attach a screenshot of any new tests passing locally

For importlib_metadata - even in Python 3.8 this worked:

$ python
Python 3.8.20 (default, Sep  7 2024, 18:35:08) 
[GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from litellm._version import version
/home/mikolajz/.virtualenvs/litellm/lib/python3.8/site-packages/pydantic/_internal/_config.py:345: UserWarning: Valid config keys have changed in V2:
* 'fields' has been removed
  warnings.warn(message, UserWarning)
>>> version

For mypy - I no longer had an error reported in my code.
