Amrith Kumar bb436d3373 Make use of Ubuntu Cloud Archive switchable
The trove development environment is typically a linux VM within which
openstack is installed, and trove launches guest vm's within that
environment. To make it possible for these vm's to launch in one human
lifetime, one must set vt/x and enable nested hypervisors to use with
kvm; qemu emulation will take way too long.

The new libvirtd (v2.5.0) in Ubuntu Cloud Archive doesn't handle
nested hypervisors well and if you use it, you end up with a guest
hanging on the GRUB line.

To enable that use-case, we provide ENABLE_UBUNTU_CLOUD_ARCHIVE which
the trove developer can set (to False) before running devstack.

# being used as ephemeral ports by the system. The default(s) are 35357 and
# 35358 which are in the Linux defined ephemeral port range (in disagreement
# with the IANA ephemeral port range). This is a workaround for bug #1253482
# where Keystone will try and bind to the port and the port will already be
# in use as an ephemeral port by another process. This places an explicit
# exception into the Kernel for the Keystone AUTH ports.
