While implementing new features and fixing bugs, I noticed that some APIs and DTOs have parameters, values or headers that were added after the implementation was done in S3Mock, or S3Mock never supported all parameters, values and headers in the first place.

• Go through all APIs and DTOs.
• Make sure that all headers, parameters and return values are supported (if possible) and (integration) tested.

Just one example:

S3Mock should support parameters in ListBuckets requests.
S3Mock's implementation of the ListBuckets API currently ignores all parameters:
