[BUG] init is no longer a top-level attribute of the pinecone package

[Rodrigo Pedro]

I'm getting the following error when initializing the RebuffSdk class in Python.

`Traceback (most recent call last):
File "myfile.py", line 91, in run

AttributeError: init is no longer a top-level attribute of the pinecone package.

Please create an instance of the Pinecone class instead.

Example:

import os
from pinecone import Pinecone, ServerlessSpec

pc = Pinecone(
    api_key=os.environ.get("PINECONE_API_KEY")
)

# Now do stuff
if 'my_index' not in pc.list_indexes().names():
    pc.create_index(
        name='my_index', 
        dimension=1536, 
        metric='euclidean',
        spec=ServerlessSpec(
            cloud='aws',
            region='us-west-2'
        )
    )`

Thanks for raising this issue. We need to update our usage of pinecone-client since we upgaded to 3.0.

@mehrinkiani, I think it would make sense for you to fix this as part of #92. Or if you think it'd be faster, you could open a PR to fix just this.

Thank you @ristomcgehee. I have opened a new PR #106 to fix this.
