This patch makes necessary changes to devstack manila
plugin in order to be able to run IPv6 scenario tests.
Part of the changes included the dependency of
neutron-dynamic-routing plugin and the installation
of quagga, so routes in devstack host can be created
automatically for each router and private network
created by tempest during the tests.
Also, added a new config option "override_ip_for_nfs_access"
for manila tempest plugin that overrides the access rules used
for NFS scenario tests. This option can be set by exporting the
environment variable "OVERRIDE_IP_FOR_NFS_ACCESS" with the
intended value before running devstack.
This change is enabled by a following change and
tested alongside a change on manila-tempest-plugin
project.
Please note that we are temporarily disabling IPv6
functionality in Host-assisted Share Migration, as
the Data Service is not able to handle IPv4 + IPv6
scenarios.
