test: mark some tests as integration in Faiss and Qdrant

[anakin87]

Related Issues

For some integrations, we don't have integration tests.

For Faiss and Qdrant, we have them, but they were not correctly marked.

Proposed Changes:

• mark integration tests
• add missing integration tests workflow: runs integration tests and save combined coverage

How did you test it?

CI

Notes for the reviewer

Despite the git diff, I just moved some tests around
