die() all along...

Avoid uploading trove guest image twice

When creating the trove datastore, get the guest image id from glance.
The trove guest image gets uploaded along with all the other
images specified in $IMAGE_URLS. It is not necessary to upload
it again in init_trove.

Also: add xenapi case to stackrc for trove guest image

vxlan default ml2 tenant network type

ovs vxlan become supported on most distribution and provides
isolated `multi tenant` networking without special `vlan` aware switch.

In single node deployment you will just see the br-tun ovs bridge
created.

In multi-node setup you might need to adjust the MTU settings.

If your physical switch supports >=1550 MTU size
 probably you will not see any issue.

If your guest image honors the MTU size offered via dhcp,
you can adjust your dnsmask settings with the correct (likely 1450 byte)
MTU size.

cirros (udhcp) does not honors these setting, you might need to
set lower MTU size on br-ex and/or adjust network_device_mtu option
in your local.conf.

The default changed, because it will be used with the multi-node neutron
jobs.

If you want the original behavior for whatever reason add these to your
`local.conf`:
ENABLE_TENANT_TUNNELS=False
Q_ML2_TENANT_NETWORK_TYPE=local

Workaround for overwriting setuptools on RHEL

This old setuptools egg-info file causes havoc and really weird pip
install errors.  I think possibly not everyone has the
python-setuptools package installed, so it may only appear in some
situations.

Resolve circular dependency when tracking dependencies.

When TRACK_DEPENDS=True, there is a circular dependency wherein virtualenv is
used to install virtualenv before a virtualenv has been established.
TRACK_DEPENDS does not work in any use case without this fix.
