feature request: allow specifying environment variables

[Trevoke]

Hi, thanks for this package!

I'm working on a project now that has some testing behavior managed by environment variables, and it would be nice to be able to manage this as state through the transient menu.

Thanks!

some testing behavior managed by environment variables

Are these ExUnit flags or application specific?

We already have some flags under different level[1], so transient won't show them by default. I am ok adding it under a higher level (5 or higher perhaps)

Application-specific. Things to prepend to the mix test call.

Examples:

• CI=true mix test (CI)
• LOG_LEVEL=5 mix test (LOG_LEVEL)
• DYLIB_PATH=/home/foo/bar/lib CLANG_PATH=/usr/bin2/cc mix test (DYLIB_PATH and CLANG_PATH)

Further - I see (and it makes sense) that we have different mix commands for testing and debugging... But I would like to be able to apply dynamically those ENV variables to both without having to change two variables.
