Auto merge of #6531 - peret:outdated-filter-dependencies, r=segiddins

Add option to filter gem-dependencies from output of 'bundle outdated'

Resolves #5366 by adding a new option '--filter-dependencies' to `bundle outdated`. When present, `outdated` will only check the `gemfile_specs` and skip the `dependency_specs`.

(cherry picked from commit 4eb981a)
