Add missing ssl related arguments to Redis from_url method

[jonathan-h-grebe]

solves #12149, the gist of which is:

• a Redis client (redis.Redis) can be obtained by using either its constructor, or from_url method
• connection options can be specified as arguments to either
• some of those options (eg ssl_ca_data) were missing as defined parameters for from_url
• this caused mypy to give false positives those missing SSL options were specified as kwargs to from_url

Change Details

To fix the issue, following 9 options were added as params to from_url

• ssl_ca_path
• ssl_ca_data
• ssl_password
• ssl_validate_ocsp
• ssl_validate_ocsp_stapled
• ssl_ocsp_context
• ssl_ocsp_expected_cert
• redis_connect_func
• credential_provider

Thanks! This becomes a bit repetitive, maybe we should use Unpack[] with a TypedDict (PEP-692) to define these kwargs?

Good point - those (almost) identical parameters being repeated 5 times do seem a bit much.

However, as TypedDicts don't support default values for keys, it wouldn't be possible to define the parameter defaults.
We could get around that by defining a dataclass, but I think that would quite an impact on existing code bases, having to switch from dict to class based syntax.
