In Mongoid master branch, there is a command .evergreen/update-evergreen-configs which relies on this line:

$: << File.join(ROOT, 'spec/shared/lib')
require 'mrss/eg_config_utils'

However, it does not appear that eg_config_utils has been committed to MRSS master yet:

https://github.com/mongodb-labs/mongo-ruby-spec-shared/tree/master/lib/mrss

Please kindly commit, thanks!
