Add integration for Marqo vector store

[sky-2002]

This PR adds marqo as a vector store to GPTCache. It was requested here in marqo's issues.

Important:

• Currently, this integration would work with marqo version 1.5.0
• To run smoothly, install client marqo==2.1.0 with pip install marqo==2.1.0. I could not use this version based format in import_marqo function as specified. Would appreciate suggestions on this.
• Marqo 2.0 still has to implement some features which are present in 1.5.0, I will update this integration when they release those features in version 2.0 onwards.

Discussions and suggestions are welcome!

Note: I have tested the functionality individually. But due to open AI credits issue, could not test it end-2-end, would be great if someone could do that.
