feat: improve sensitive data handling by fsspec connectors

[rbiseck3]

Description

Building off of PR #2179, updating fsspec based connectors to use better authentication field handling. This PR adds in the following changes:

• Update the base classes to inherit from the enhanced json mixin
• Add in a new access config dataclass that should be used as a nest dataclass in the connector configs
• Update the code extracting configs out of the cli options dictionary to support the nested access config if it exists on the parent config
• Update all fsspec connectors with explicit access configs given what each one's SDKs support
• Update the json mixin and enhanced field to support a name override when serializing/deserializing from json/dicts. This allows a different name to be used for the CLI option than what the name of the field is on the dataclass.
• Update all the writes to use class-based approach and share the same structure of the runner classes
• Above update allowed for better code to be used in the base source and destination CLI commands
• Add in utility code around paring a flat dictionary (coming from the click based options) into dataclass-based configs with potentially nested dataclasses.

Slightly unrelated changes:

• session handle removed from pinecone connector as this was breaking the serialization of the write config and didn't have any benefit as a connection was never being shared, the index used simply makes a new http call each time it's invoked.
• Dedicated write configs were created for all destination connectors to better support serialization
• Refactor of Elasticsearch connector included, with update to ingest test to use auth

TODOs

• Left a #TODO in the code but the way session handler is implemented right now, it breaks serialization since it adds a generic variable based on the library being used for a connector (i.e. googleapiclient.discovery.Resource) which is not serializable. This will need to be updated to omit that from serialization but still support the current workflow.

I've gone through everything. A lot to go through. But works well and I didn't see anything suspicious. Looks good. Really liking the access_configs instead of access_kwargs.
