feat: Qdrant storage connector

[Anush008]

Description

This PR adds support for Qdrant - https://qdrant.tech/ to be used as a storage connector.

Tests

• Tests have been configured using a Qdrant server at port 6333 for tests/test_storage.py and tests/load_archival.py.
• A CI service has been set up to launch Qdrant.

If a Qdrant instance is not running or the client library is not installed the Qdrant tests are skipped.

To run Qdrant server

docker run -p 6333:6333 qdrant/qdrant

Hi @cpacker. Could you please take a look when possible please?

Thanks for submitting this PR! We are happy to support more storage backends, however since we are a fairly small team, we ask that external contributors continue to maintain their storage integrations over time. MemGPT is under active development, so it's possible that the storage connectors will need to be refactored or modified in the future, and our team can only commit to maintaining the default storage connectors.

Hi, @sarahwooders. I've rechecked the implementation as per recent updates. Please take a look when possible.

An update.

• The dependency on the qdrant-client library is now optional with a qdrant extra.
• Updated and verified the tests.
• Qdrant container for CI is set up.

Failing https://github.com/cpacker/MemGPT/actions/runs/9253848636/job/25755429975?pr=1023 appears to be due to missing credentials.
