Deprecates username and password from boot time registration

The username and password combination is considered insecure to store in
the metadata passed to the stack as they can easily be obtained and
possibly used in an unathorized manner by logging into one of the
registration systems. The use of an activation key is more desirable
as it can only be used in conjunction with subscription-manager to
register a RHEL system.

This patch deprecates the username and password support from the script
that registers RHEL with either Satellite or RH Customer Portal during
boot-time.  This patch also adds a warning if the username and password
combination is used in the stack metadata. The documentation and examples
have also been updated to warn operators of the deprecation of username
and password.

This patch does not affect the username and password support for
registration activities while building images with diskimage-builder.

+SECURITY WARNING:
+-----------------
+While the image building workflow will allow you to register with a username
+and password combination, that feature is deprecated in the boot process via
+Heat as it will expose your username and password in clear text for anyone
+that has rights to run heat stack-show.  A compromised username and password
+can be used to login to the Red Hat Customer Portal or an instance of
+Satellite.  An activation key can only be used for registration purposes using
+the subscription-manager command line tool and is considered a lower security
+risk.
