Please make _run_test_class and _run_test_method public

It's trivial to override the executor in Test::Class::Moose::Runner to make a custom subclass, but when subclassing Test::Class::Moose::Executor::Sequential, I have to use the private methods _run_test_class and _run_test_method with my before modifiers.

It would be lovely if those were made public so I didn't feel too guilty about those. If those were public, I could easily publish modules which allow verbose output like the following (without needing to extend functionality with PRs such as #76):

Seems like a good idea. We should probably also have a public run_test_instance too.

I also realized that for this to really function properly you need a way to pass roles to be applied to the executor into the runner class. Right now it hard codes the Sequential & Executor class names, so there's no way to tell it to use a subclass. Allowing arbitrary roles to be applied to the executor would make it easier for folks to write plugins.

This is done in v0.92.
