Cisco plugin cannot create ports for non-admin VMs

[Michael Chapman]

https://github.com/openstack/neutron/blob/stable/grizzly/quantum/plugins/cisco/models/virt_phy_sw_v2.py#L204

_get_instance_host is attempting to use the
admin username and password with the user's
tenant, which leads to 401 auth errors from
Keystone when attempting to determine the
instance host from nova. This prevents users
that belong to tenants where the admin
user does not have a role from being able
to launch any VMs.

    Fix auth issue in get_instance_host

    _get_instance_host was attempting to use the
    admin username and password with the user's
    tenant, which leads to 401 auth errors from
    Keystone when attempting to determine the
    instance host from nova.

    This patch reads the admin tenant from the same
    place as the username and password and uses that
    instead. It also removes the keystone call that
    was used to determine the tenant_id from the name,
    since that is no longer needed.

From a review comment: "The code in the master branch was changed as a result of other work, so this direct change directly to Grizzly makes sense."

Mark, in such case, please target to Grizzly series and mark master task as "Invalid", as I did now.
