Add a file or local application source

[Jérôme Vizcaino]

Building from url or git pulls/clones everytime the build process is started.
Talking with Sam on IRC, he suggested to add a local or file source to the build process.
This way, Docker would efficiently use its cache and trial & errors rebuilding part of the images would be faster.

This is a blueprint since its a feature request, not a bug. We use blueprints for tracking feature changes. Please submit a blueprint. I think this would be a great improvement. Closing as invalid, as this is not a bug.

There is already a patch in the queue that implements this, it was simply missing a bug id... here it is :)

    Add local directory or file for source build

    This change allows using a local directory or tarball to build from
    sources by specifying the 'local' type in your kolla-build.conf:

        [keystone-base]
        type=local
        location=/home/martin/src/keystone

        [neutron-server-plugin-networking-cisco]
        type=local
        location=/tmp/networking-cisco.tar.gz
