Solves #946 by adding type definitions for the optional annotations attribute for resources.

Also adds tests to validate the schema -> SDK typings and creation of a resource with annotations

Hello. Thank you for your work on this.

Got my eyes on this PR and have updated it to the latest, as well as added annotations everywhere as specified by the spec.

Need to add some tests to lock it down for all the other types which now include annotations.

Will follow this through.
