This enables the dynamic generation of the list of rules files for prometheus, driven by the rules added in the appropriate tree under .Values.conf.prometheus.rules. This removes the necessity of adding the file name manually in addition to defining the rules in the rules tree, which should reduce overhead associated with adding new rules for prometheus to evaluate Change-Id: Ib768a252c5ea4f2d099df534c3ffcfb2949d7481
