Add inference plugin and tests (#370)

## Problem

We want to ship inference as part of the core SDK

## Solution

Add a dependency on v1.0.2 of the inference plugin, which includes a
recent fix to plugin installation for use with the GRPC client.

## Usage

The plugin should automatically be installed and available for usage.

```python
from pinecone import Pinecone

pc = Pinecone(api_key='key')

embedding_model = "multilingual-e5-large"
embeddings = pc.inference.embed(
    model=embedding_model,
    inputs=["The quick brown fox jumps over the lazy dog.", "lorem ipsum"],
    parameters={"input_type": "query", "truncate": "END"},
)
```

## Type of Change

- [x] New feature (non-breaking change which adds functionality)

## Test Plan

See tests passing.
