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.

Use example settings in horizon repo as local_settings.py

The current horizon_settings.py in devstack is out-of-date and we
tend to forget to update this file. This commit changes devstack
to use the example settings in horizon repo.

Don't clobber all iSCSI connections during nova cleanup

The existing cleanup_nova() code inadvertently logs out of all iSCSI
connections on the machine because it does not pass the target name
as the -T parameter. This patch changes it to step through the targets
that match the pattern, logging out of each individually, and following
up with a delete op to cleanup the database.

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/

Split disk creation out of configure_swift()

Grenade needs to be able to configure Swift without initializing the
backing disk files.  Move it into create_swift_disk() and call
from init_swift().

Also move start of n-obj (if swift3 is not enabled) to start_nova().

add emacs shell-script tagging

for files that don't start with a #! or end in .sh, the added tags
are nice for emacs users to automatically switch to the right mode.

Make Swift *_PORT_BASE configurable

DevStack's Swift port defaults changed in the Grizzly cycle, we need to
put it back to complete the upgrade without going through the ring build process.

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 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.

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.
