refactor helm files to use namespace prefix

refactor helm files to use namespace prefix

-removed the full namespace from each template.  better lets us reuse
variables.
-made secret end up in a configurable namespace
-fixed some bugs where secrets were missing
-updated createAll and delete to make use of namespace prefix
removing the need for seds to replace the word onap.

*** all containers at this point come up in my env. except for
aai model loader which is failing cause its still at 1.0
and its trying to talk to a 1.1 sdc and it doesnt auth properly. ***
