Remove `configured_scheme` from OpenDalStorage::{S3, Azdls}

[CTTY]

Is your feature request related to a problem or challenge?

Since now Storage API accepts fully-qualified locations, we no longer need to check schemes in OpenDalStorage::{S3, Azdls}

Describe the solution you'd like

1. We should remove configured_scheme from OpenDalStorage::{S3, Azdls}
2. In OpenDalResolvingStorage, we maintain a map<Scheme, Storage>, and since now we can have multiple schemes mapped to one storage instance: ("s3", "s3a", "s3n" -> S3Storage), we need to update this structure accordingly
