[Cosmos] Clean up public surface area

[simorenoh]

We have recently found that some of the arguments and options that we expose in our public surface area are not relevant to several methods even though they are listed in their typehints. This PR aims at cleaning that up so that customers can be aware of the exact options that are available to them in every single one of our methods. Most of these changes revolved around the session_token, etag, match_condition and response_hook arguments. Some notes on these:

Session tokens only apply to item-level operations. Control plane operations are strongly consistent so this option has no relevance for those operations.

Etags and their relevant match conditions only apply to item-level operations, and within those only apply to replace and delete operations that deal with single items. Their typehints have been removed from all other instances where they were referenced.

Response hooks in the Python SDK will always take in two things: the response headers (dictionary of string -> string) and the response (dictionary of string -> any). Typehints have been updated to reflect this, and some wrong uses of response hooks were removed from query-type methods since calling the response hook at that point is broken behavior that does not in any way reference the results of the query and were using the wrong last_response_headers that would come from other operations at that point in the code.

The following were cleaned up:

cosmos_client.py

• Removed session_token option from the list_databases, query_databases methods as they are not relevant to them.
• Removed session_token, etag, match_condition options from the create_database, create_database_if_not_exists, delete_database methods as they are not relevant to them.

database.py

• Removed session_token option from the read, list_containers, query_containers methods as they are not relevant to them.
• Removed session_token, etag, match_condition options from the create_container, create_container_if_not_exists, delete_container, replace_container methods as they are not relevant to them.

container.py

• Removed session_token option from the read method as it is not relevant to this operation.
• Removed etag and match_condition options from the upsert_item, create_item, execute_item_batch, delete_all_items_by_partition_key methods as they are not relevant to them.
• Fixed the response_hook typehints to be more accurate and removed their direct use before the queries get executed for the read_all_items, query_items_change_feed, and query_items methods.

The same changes have been made to the async client's relevant files.

Also went ahead and fixed some tests I happened to see, as well as removing the mention of "Lazy" indexing since it has been unsupported for almost 5 years now.

PR Overview

This PR cleans up the public API surface by removing unsupported parameters (such as session_token, etag, and match_condition) from various methods and by updating typehints and response hook usage. It also removes legacy functionality (e.g. lazy indexing) and converts synchronous test clean‐up calls to their asynchronous counterparts.
