Change rubygems/bundler source to use bundler CLI about licensed HOT 2 CLOSED

It looks like the following to pull all the information would work

1. bundle check to surface any errors
2. bundle show --paths to get folders containing dependency specifications
3. get the spec path from the folder
4. Gem::Specification.load(spec_path)

Putting this on hold for now.

There are some design decisions on Bundler that make it pretty hard to use exclusively from CLI for our usages. After a few days of diving into Bundler and rubygems, I've found it easier to work around their API than it is to work around the CLI.

Bundler's configuration hierarchy favors local bundler configuration over ENV meaning that it's really difficult to maintain licensed behavior of excluding [:development, :test] groups from results. This goes against the expected hierarchy of specificity where settings on a command override all settings from the environment.

Loading dependencies fully from CLI commands introduces some performance penalties. If the implementation isn't significantly simpler from using the CLI, there's no reason to take a performance penalty as well.

If the bundler source continues to cause issues in the future then perhaps this issue should be revisited.
