Subject: [PATCH] feat(url_resolver): Allow a developer to customize their
 package prefix

Allow a developer to specify a package prefix where the 'package:' dart urls
will be resolved. By default this will be '/packages' keeping the current
behavior, but allows for flexibility of different environments where a
developer may not control their directory structure.

Closes #3794
