Adds support for the openapi-processor mapping.yaml configuration file.

• automatically selects the json schema of the mapping.yaml to provide editing support (autocompletion & validation). Note that the openapi-processor-mapping: v[x] line in the mapping.yaml is used to detect it.
• marks the mapping.yaml with an openapi-processor icon to separate it from the openapi yaml file(s) (includes new ui icon)
• navigate from the package-name configuration in the mapping.yaml to the package with the generated sources (if the target package exists).
• navigate from an endpoint path mapping in the mapping.yaml to the generated interface method (via a standard interface icon).
• navigate from an OpenAPI endpoint path to the generated endpoint interface methods (via a standard interface icon).
