[Feature] Add memory properties to StrayCat

[valentimarco]

Description

Related to issue #818, point 3

With this PR, I added new properties to StrayCat and some types (YES):

1. user_message(self) -> str, return the query of the user
2. memory_vector_client(self) -> QdrantClient, return the QdrantClient (Is is useful? personally yes, if i want to do some strange stuff...)
3. <name collection>_memory(self) -> VectorMemoryCollection, return a VectorMemoryCollection instance of the selected memory. Usuful to search, add or destroy vectors in a specific collection.

Nothing new is added, "old piero" did a great job when designing the VectorMemory!

To search points use recall_memories_from_embedding(embedding, metadata=None, k=5, threshold=None ).

Maybe #848 should be method of VectorMemoryCollection??

What if in the future we want to give the possibility to add other collections to the memory?
I'd suggest something like:

@property
def memory(self):
    return CheshireCat().memory.vectors

Great question! I only thought about the 3 collections...
The name should be vector_memory

@property
def vector_memory(self):
   return CheshireCat().memory.vectors

So you have:

1. direct access to the main collections.
2. direct access to the VectorMemory.
   At the moment you can access it like so : cat.memory.vectors.<something>.

Sounds good @valentimarco, will review in the next days thanks :D
