Implement AWS plugins

[pokryfka]

Implement plugins to check (and set as subsegments metadata) AWS environment.

For segments, the aws object contains information about the resource on which your application is running. Multiple fields can apply to a single resource. For example, an application running in a multicontainer Docker environment on Elastic Beanstalk could have information about the Amazon EC2 instance, the Amazon ECS container running on the instance, and the Elastic Beanstalk environment itself.

the plugin instances (or types?) should be passed when creating XRayRecorder instance which would use them to set AWS for all the segments it creates.
