Metadata defintions in etc/metadefs are not included in Python packages

[Ian Cordasco]

The files in etc/metadefs in the Glance repository are not included in either the tarball or wheel when one runs

    python setup.py sdist bdist_wheel

These should be included by default and installed so they can be used. Since wheels should not be allowed to write to paths outside of the directory the package is installed in,

    glance-manage db_load_metadefs

Should also look in the installed directory path for etc/metadefs when loading them.

This is a problem in every version of Glance that was meant to include those metadata definitions. Since this does not prevent functionality from working (since a user could download the files to /etc/metadefs and run the command), I do not think this has backport potential.

lifeless was kind enough to provide http://docs.openstack.org/developer/pbr/#files as a reference for the best way to do this with pbr. It needs some testing first to make sure we get the right solution.

    Include metadefs files in all packages

    Previously, metadefs were only shipped in archives of the entire
    repository. There's been a recent push in the operator community to
    deploy from source, including building wheels and installing using them.
    In order for the deployers to take advantage of metadefs as intended.
