Passing cert file in python storage_options

[sbonthala-0714]

I have a custom https s3 end point.Wanted to check if any one of the below options are possible.

1. Is there a way to skip ssl verification similar to how requests module that can be set in storage_options?

2. If the above option is not possible, is there a way to pass cert path in the storage_options without setting SSL_CERT_FILE env variable.

Currently delta rs is able to connect to custom https s3 endpoint with out setting os environment variable.

I am using python delta lake version 0.25.4
