Add a new provider `AwsS3EntityProvider` as a replacement for the now deprecated
`AwsS3DiscoveryProcessor`.
The new provider will scan configured S3 buckets (with optional) prefix and
add `Location` entities for all discovered catalog files.
These `Location` entities will then be processed as usual.
At each execution, the provider will apply a full mutation, replacing all previous
entities with the new entities/state.
