Subject: Add the ability to specify multiple extension directories
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=14069f9e0abb31b784050074165b3eeb354ab4ea;p=openstack-build%2Fneutron-build.git

Add the ability to specify multiple extension directories

This allows for a colon-separated list of extension directories that will be
loaded at startup.
