Allow type in common stanzas or default to exitcode-stdio-1.0

[daig]

Currently, cabal complains:

Unknown field: "type"
Test suite "my-test" is missing required field "type" ....

I don't see any reason that type should be excluded from common stantzas - does it make sense to add?

A minor annoyance, but in practice the boilerplate encourages monolithic test files

@daig there is a simple reason: common stanzas currently only allow fields which are applicable to all stanza kinds, iow, the common denominator; this was a deliberate design decision to simplify the semantics & implementation for the first iteration of common-stanzas.

See also #2832 for a discussion of how to model "typed common" stanzas which is what we'd need to address this.

Thanks, I had missed that discussion. It does make sense for a first iteration and I'm much glad to have existing common stanzas as an 80% solution. What is the best place to track discussion on the next iteration for common stanzas?

@daig keep watching this ticket and the original #2832; if any progress is made those tickets are very likely to get updated as well

I think this is subsumed by #7459
