ssh instance validation add options for Neutron

This is the first part of the patch series which
 implements multiple ssh instance validation strategy.

This patch adds the new config options and have the effected
test classes to prepare the basic neutron resources for usage.

The default is using the fixed ips for connection, but
on the devstack side the configuration options are configured,
for neutron usage.

Implements: blueprint ssh-auth-strategy
