support swagger-core 2.0.0

[pjfanning]

I have a partial implementation ( https://github.com/swagger-api/swagger-scala-module/compare/develop...pjfanning:swagger-core-2.0.0?expand=1 )

The issues are:

• fixing the required setting for schema properties (API change in swagger-core 2.0.0; you need to set a list of required items on the parent property, but the ModelConverter doesn't have access to the parent property)
• the support for scala enums is broken
• get test coverage back up

Is there any update on support swagger-core 2.x?

I have a fork that supports this - https://github.com/swagger-akka-http/swagger-scala-module/
