Run audit automatically on bundle or bundle install command

[Urist-McUristurister]

Right now to audit the gems, you have to run a command manually or by using git hooks.

It really would be a nice touch to have an option to install bundler-audit as a bundler plugin (or maybe release it as a separate gem?), which would execute bundle-audit check -u -q on every bundle or bundle install command (maybe check if Gemfile.lock have actually changed, too?..), then either print a message and exit(1) on failure, or silently move on if everything is good.

Human memory is very unreliable, not everyone can remember to manually run the audit every time the Gemfile changes. This feature could really help improve the security.

Appears that we just need to add a top-level plugins.rb file and add a after-install hook?

The plugin would be opt-in so you'd still need to add plugin 'bundler-audit' to your Gemfile.
