WIP: Hie bios docker support

[fendor]

Currently with hard-coded arguments for the output file in docker mode.
Does not work for me, in a project with docker enabled, I currently get the error message:

⨯ hie-bios check src/Lib.hs                                               
hie-bios: hie-bios: can't find a package database at /opt/ghc/8.6.4/lib/ghc-8.6.4/package.conf.d

The output file looks like this for me:

⨯ cat out

--interactive

Where does that path come from?

[mpickering]

Perhaps this will never work of the packaged are only in scope inside the container. You would have to run the IDE inside the container as well.

[fendor]

No idea where this path comes from.

Yeah, that would definitely work.

[mpickering]

And if you run the IDE inside the same container then the stack support will work without any modifications I think.

[mpickering]

Closing as out-of-scope.
