Implement user-defined tenant for neutron nets

Default networks were previously hardcoded to use
"admin" as the tenant, regardless of user input.
This patch is a workaround because nailgun creates
neutron_config with admin tenant hardcoded as well.

FIXMEs were added to indicate what code needs cleanup
after nailgun is patched.
