errors: add hints to solve the errors, if possible

We can take as an example the way Elm handles errors in the compiler: https://elm-lang.org/news/compiler-errors-for-humans

DVC already does this in some extent but I'm sure there's room for improvement on this one.

Also, thinking about introducing another method for logger: hint, that will output something like:

ERROR: this stuff failed
HINT: you could try X or Y prevent this from happening

(HINT could be colored in purple)

Ivan was helping me on discord and it seems relevant:

My error:
ERROR: failed to run command - file/directory 'data/csvs/raw_zipped_csvs' is specified as an output in more than onestage: run/01_download_LC_csvs.dvc
data/csvs/raw_zipped_csvs.dvc

Potential Hints:
HINT: try running dvc pipeline show --ascii data/csvs/raw_zipped_csvs.dvc
HINT: remove 'data/csvs/raw_zipped_csvs' as an output from "run/01_download_LC_csvs.dvc" or
"data/csvs/raw_zipped_csvs.dvc" with dvc remove

First step: catch that exception on dvc run and if we only have 1 other stage that has that output, then raise a new more helpful exeption that looks something like:

ERROR: failed to run command - file/directory 'data/csvs/raw_zipped_csvs' is already used by `data/csvs/raw_zipped_csvs.dvc`, consider using another output name
