The password to access telemetry and healtcheck APIs in PDP-D are different depending if AAF is used or not.

AAF requires an specific syntax for the username which  non-AAF auth does not require when AAF is disabled.

In order to not require client reconfiguration when AAF authentication is used or non-AAF authentication when invoking the APIs for demo purposes, we'll unify to a generic set of credentials that conform to the most constraint one (AAF in this case which is new in the release).  demo@people.osaaf.org will be set up by default for ONAP installations for AAF.   We will use the same default credentials for when AAF is not installed.
