cloud/aws: exposed additional options to config;

This exposes additional options for AWS clients to the config files.
These include:

- Disabling request compression and min compression request size for cloudwatch
- Disabling response checksum validation and accepting gzip compression for dynamodb
- The usePathStyle setting was documented for S3 (but it was already exposed before)

These settings are needed when talking to services implementing the AWS
API like localstack or ScyllaDB as these services sometimes can't map
all features exactly.
