Unrecognized property 'documentation' issue resolved by adding validation rules

[gordana16]

The Serverless Framework has added http event validation since version 2.6.0 without including 'documentation' property. Plugin developers are encouraged to extend validation schema by adding validation rules for additional properties supported by plugin.

This PR resolves "Unrecognized property 'documentation'" triggered by serverless framework (since version 2.6.0) by adding JSON schema definition for 'documentation' property inside 'serverless-aws-plugin' constructor.

@gordana16 awesome work! it's quite hard to review though because the linting rules were changed (I'm not a maintainer btw, just interested in the topic :p)
