Install `-prof` packages? about docker-haskell HOT 4 CLOSED

Sounds reasonable, though if -prof is significantly bigger, it may make more sense to add a variant instead? I think we are stuck with quite large images due to GHC + dependencies, so the value of a -slim is questionable to me, but I have not looked at the numbers recently.

• Rust has e.g. 1-slim-stretch tag, which downloaded a layer of size 371.3MB for me.
  • their slim vs stretch differ mainly in the choice of base image.
• Haskell 8.4.4 main layer is is 244MB,

I think we can afford -prof in normal image and -slim can stay slim. That would be good for consistency with other official images. Our current image is what other call "slim": no extras.

I'm planning to implement this suggestion. I have seen people expect it recently and I think that is fairly reasonable. So..

• Defaults will include profiling
• Add -slim variants (for Debian only) which do not include profiling support and are based off of the debian -slim variants.
• Alpine + Windows will also include profiling (when they are supported). I do not think I will add a slim variant here.

The profiling files take the image from 1.73GB -> 2.46GB (740mb) for 9.2 on Debian buster. Not the worst I guess. I think minimising image size is overrated.

I will ponder this more. On the flip side there has been little interest in including profiling libs.. hmm

Decided to just pull the trigger as described above.
