Feat: Utils add wipe qdrant and new stats command

[dbzoo]

Add support for deleting the collection created in a qdrant vector datastore.

vectorstore:
  database: qdrant

I did not change the name of the store from make_this_parameterizable_per_api_call for upgrade compatibility.

This collection should be named something more appropriate. I suggest data_embeddings. This is how its named in the Postgres database. Renaming this store will be a breaking upgrade for those who have ingested data.

Test output

% ls local_data/private_gpt/qdrant/collection 
make_this_parameterizable_per_api_call
% PGPT_PROFILES=local make wipe
poetry run python scripts/utils.py wipe
20:31:23.378 [INFO    ] private_gpt.settings.settings_loader - Starting application with profiles=['default', 'local']
Collection dropped successfully.
% ls local_data/private_gpt/qdrant/collection
%

Stats command

This gives some simple metrics about the data, index and vector stores.
