Ron Stone f125a8b892 Remove spurious escapes (r8,dsR8)
This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

=======================================================
 Local Docker Registry Authentication and Authorization
=======================================================
Authentication is enabled for the local Docker registry. When logging in,
users are authenticated using their platform keystone credentials.
For example:
.. code-block:: none
$ docker login registry.local:9001 -u <keystoneUserName> -p <keystonePassword>
An authorized administrator ('admin' and 'sysinv') can perform any Docker
action. Regular users can only interact with their own repositories (i.e.
registry.local:9001/<keystoneUserName>/). Any authenticated user can pull from
the following list of public images:
.. _kubernetes-admin-tutorials-authentication-and-authorization-d383e50:
- registry.local:9001:/public/\*
- registry.local:9001:/k8s.gcr.io/pause
- registry.local:9001:/quay.io/jetstack/cert-manager-acmesolver
The **mtce** user can only pull public images, but cannot push any images.
For example, only **admin** and **testuser** accounts can push to or pull from
**registry.local:9001/testuser/busybox:latest**
.. _kubernetes-admin-tutorials-authentication-and-authorization-d383e87:
---------------------------------
Username and Docker compatibility
---------------------------------
Repository names in Docker registry paths must be lower case. For this reason,
a keystone user must exist that consists of all lower case characters. For
example, the user **testuser** is correct in the following URL, while
**testUser** would result in an error:
**registry.local:9001/testuser/busybox:latest**
.. note::
Use of the auto-generated self-signed certificate for the registry
certificate is not recommended. If you must do so, then from the central
cloud/systemController, access to the local registry can only be done using
registry.local:9001. registry.central:9001 will be inaccessible. Installing
a |CA|-signed certificate for the registry and the certificate of the |CA| as
an 'ssl_ca' certificate will remove this restriction.
