Add Schemas to supported AWS services

[tomgi]

Hi, I'm using ddtrace AWS integration to be able to track every interaction with AWS services in Datadog.

I've noticed that the calls to Schemas API seem to be missing though.

I think simply adding Schemas to the list of supported AWS services should enable that tracking.

aws-sdk-schemas gem uses AWS Seahorse Client (like all the other AWS services), so I reckon it should "just work".

I checked that :Schemas exists in ::Aws.constants, so it won't get filtered out in

dd-trace-rb/lib/ddtrace/contrib/aws/patcher.rb

Line 34 in 1343922

available_services = ::Aws.constants & SERVICES.map(&:to_sym)
