Adjust config kwargs to Pinecone and PineconeAsyncio

[jhamon]

Problem

We want to deprecate a few kwargs and give more helpful error messages.

Solution

• Deprecate config and openapi_config kwargs; as far as I know these were only used for tests. They have not appeared in documentation. It adds quite a bit of complexity trying to merge configuration from all these sources so going forward we would prefer to just expect configuration from a single source, which are named kwargs.
• Add NotImplementedError messages that clearly explain some features that are not implemented yet for PineconeAsyncio. This is preferrable to allowing users to pass kwargs that have no effect, then getting frustrated when they seem not to work.
• Give more informative error when it looks like the user has passed an invalid value as the host

Type of Change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update
