Change default PUBLIC_NETWORK_NAME/DEFAULT_FLOATING_POOL name

This patch changes the default network name/floating pool from nova
to pubic as the name public makes more sense than nova for a public
network.

Allow a plugin specific interface_driver config in q-lbaas

Previously interface_driver for q-lbaas is hardcoded and q-lbaas does
not work when quantum plugin requires additional configuration (like
ovs_use_veth=True). This commit set up interface_driver using
quantum_plugin_setup_interface_driver function.

This commit also moves a script related Quantum service plugin to
lib/quantum_plugins/services/

refactor the install/configure split

configure remains just to generate configs, install now
gets the setup_develop in addition to the git clone. This lets
use remove configure_glanceclient as a function

Change-Id: I68e3e3973d15dc0b4f534662a4f57a9f38f69784
change the install/configure split

make setup_develop part of install so that configure is only about
config file setup.

Change-Id: I1ed58011e41c550d3ab2ba33b38cfe16adb3dde4
change configure/install split

make it so setup_develop happens in install instead of configure
to ensure that we can handle config file generation by itself.

Use sudo to remove packages

yum and others need root to remove packages

Move setup_develop call

Move setup_develop() call into the install_XXX() function as the
distinction has no real purpose.  This eliminates the configure_XXXclient()
function for Nova and Swift.

Also create install_cinderclient() as we will need it to handle dependencies
in a followup patch.
