Remove references to OpenStack Anchor

The OpenStack Anchor project is now officially retired[1].

This patch removes the references to Anchor from Octavia.
These old references were confusing new users.

======
Anchor
======
Anchor (see https://wiki.openstack.org/wiki/Security/Projects/Anchor) is
an ephemeral PKI system built to enable cryptographic trust in OpenStack
services. In the context of Octavia it can be used to sign the certificates
which secure the amphora - controller communication.
Basic Setup
-----------
1. Download/Install/Start Anchor from https://github.com/openstack/anchor
2. Change the listening port in config.py to 9999
3. I found it useful to run anchor in an additional devstack screen
4. Set in octavia.conf (root-ca.crt here is the Anchor CA)
a. [controller_worker] cert_generator = anchor
b. [haproxy_amphora] server_ca = /opt/stack/anchor/CA/root-ca.crt
5. Restart o-cw o-hm o-hk
Benefit
-------
In bigger cloud installations Anchor can be a gateway to a more secure
certificate management system than our default local signing.

Rotating Amphora Certificates
-----------------------------
For the server part Octavia will either act as a certificate authority itself,
or use :doc:`../Anchor` to issue amphora certificates to be used
by each amphora. Octavia will also monitor those certificates and refresh them
before they expire.

There are three ways to initiate a rotation manually:

Anchor
Is an OpenStack project for an ephemeral PKI system (see
https://wiki.openstack.org/wiki/Security/Projects/Anchor). In Octavia
we can use Anchor to sign the certificates we use to authenticate/secure
controller <-> amphora communication.
Apolocation
Term used to describe when two or more amphorae are not colocated on
the same physical hardware (which is often essential in HA topologies).
