    Enable developer mode

    This commit adds the ability to install cinder without a repo server.
    This pattern is lifted from the os_keystone role and allows us to
    further develop functional testing for this role.

    Add functional convergence test for os-swift role

    Adds a functional/convergence tests for os-swift including keystone,
    galera, memcache and rabbit.

    Swift testing infrastructure consists of:
    1 service container /w keystone, galera, rabbit, memcached.
    4 storage hosts (each with 2 disks)
    1 proxy container.

    This fixes a few issues to ensure the functional tests will run, such as
    delegating sysctl net.ipv4.tcp_tw_reuse task to physical host, since we
    are running swift storage inside containers for the purposes of this
    test, and the containers won't have access to make this change.

    Fixes the developer_mode settings which were incorrect.
