Kevin Howell 329843bc92 Gradle - make GenerateTask properties optional (#2185)
This allows easier creation of custom `GenerateTask`. Specifically, this makes:

 - generateModelTests
 - generateModelDocumentation
 - generateApiTests
 - generateApiDocumentation
 - withXml

optional, following the same pattern as other properties in GenerateTask.

Without this change, we get `java.lang.IllegalStateException: No value
has been specified for this provider.` until these properties are
specified for the task, when attempting to define a custom generate task
(such as one to generate API docs).
