Create and Delete tests

[omdxp]

Is your feature request related to a problem? Please describe.
Newly created files does not contain unit tests and/or integration tests with them.

Describe the solution you'd like
This feature is really good to create your unit tests alongside your newly created files (from your components to your pages to your custom functions).

Here are some samples:

rhc create -c test

It creates test files with the component.

Additional context
This also can be added to rhc.config.json as a property withTests so when creating new components or screens it can also add test files alongside them.
