Feature Request: Filter tests in a certain group

[tisonkun]

Nextest currently suppose grouping tests to run exclusively.

However, the filter DSL works in a irrelevant way, so that when I'd like to run a specific test group, I have to write the filter DSL twice and ensure they are the same.

It is possible to have a filter DSL such as group(group_name) to match all the tests in a certain group?

Maybe related to #101 but subtly different.

Thanks! Good idea and one I'd been thinking about.

One issue is that this can introduce cycles in the execution graph for the DSL interpreter, but that's not too hard to handle. Will try getting to it in the next few weeks.
