[REQ] Add ability to skip some of the web services in an openapi contract

Is your feature request related to a problem? Please describe.

Sometimes the openapi is huge and you only want a small number of web services to be included in the generator output.

Describe the solution you'd like

Configuration options:

• includeResources - Inclusive paths of resources to include. Anything outside of these would be skipped.

Example:

<includedResources>
  <includedResource>/hello-world</includedResource>
  <includedResource>/hello-world2</includedResource>
</includedResources>

• excludeResources - Paths of resources to exclude. Anything matching these would be skipped. Example:

<excludedResources>
  <excludedResources>/hello-world</excludedResource>
  <excludedResources>/hello-world2</excludedResource>
</excludedResources>

Describe alternatives you've considered

None of the other work arounds are as simple. Editing the openapi yaml is not attractive option. etc. The other exclusion options are not very declarative and seem to be bugged.

No file or test is named in the request. Start by locating the generator configuration handling and the existing exclusion options, then trace how resource paths are selected; done means includeResources and excludeResources can declaratively filter generated output and are covered by tests.
