Fix release name bug

The release name was being treated as multiple different values to
mean the same thing, when paired with the 'release_prefix'.  This
commit addresses the bug, changing all instances to use the
'release' value instead of 'chart_name' or others.

Note: This is an impacting change, in the sense that it will
cause more reliable behavior in Armada's Apply processing which
could have actual impact while upgrading components installed with
a previous version of Armada.  Previuosly undeleted FAILED releases
may now be deleted, and armada test and delete actions may now
run as expected where they didn't run before.
