[WIP] Allow before(:all) blocks to play nicely with rspec-retry
requested to merge github/fork/token-cjg/cgoddard/get-retries-working-in-before-all-blocks into master
Created by: token-cjg
Currently rspec-retry doesn't work in before(:all) blocks; specs will simply fail after one attempt, eg if one passes retry=3 to a bundle exec ...args declaration.
Inherit from RSpec::Core::Configuration to create a new configuration object that overrides the previous functionality.
Add noredink/rspec-retry as a Gemspec dependency.
This should allow rspec-retry to retry in before(:all) blocks.
