1. cmd/doctor: Add --ignore-warnings …

   When `brew doctor` is run, `brew` exits with a non-zero status if any
   warnings or errors are encountered. However, this groups warnings and
   errors together, but (as the output notes) warnings can be innocuous:

   > just ignore this. Thanks!
   
   The `--ignore-warnings` switch makes it possible for automated tools
   interacting with Homebrew to distinguish between warnings and hard
   errors.
   
   ```
   $ brew doctor --ignore-warnings
   Please note that these warnings are just used to help the Homebrew maintainers
   with debugging if you file an issue. If everything you use Homebrew for is
   working fine: please don't worry or file an issue; just ignore this. Thanks!
   
   Warning: Some installed casks are deprecated or disabled.
   You should find replacements for the following casks:
     graphql-playground
   $ echo "$?"
   0
   ```
   
   Hard errors will still cause a non-zero exit status:
   
   ```
   $ brew doctor --ignore-warnings
   Please note that these warnings are just used to help the Homebrew maintainers
   with debugging if you file an issue. If everything you use Homebrew for is
   working fine: please don't worry or file an issue; just ignore this. Thanks!
