[COMMON] Fix name generation in readinessCheck template

According to docummentation readinessCheck template accept wait_for
value in a type of list. Unfortunately in that case it generated the
init container name with -- as the name key was empty.

This commit fixes this and ensures acceptance of both simple and
extended format for wait_for value.

   Generate readiness part for a pod
   Will look by default to .Values.wait_for
+  There are two formats available.
 
-  Value of wait_for is an array of all pods /jobs to wait:
-
-  Example:
+  The simple one (where wait_for is just list of containers):
 
   wait_for:
     - aaf-locate
     - aaf-cm
     - aaf-service
 
-  The function can takes two arguments (inside a dictionary):
+  The powerful one (where wait_for is a map):
+
+  wait_for:
+    name: myname
+    containers:
+      - aaf-locate
+      - aaf-cm
+      - aaf-service
+
+
+  The function can takes below arguments (inside a dictionary):
      - .dot : environment (.)
+     - .initRoot : the root dictionary of readinessCheck submodule
+                   (default to .Values.readinessCheck)
      - .wait_for : list of containers / jobs to wait for (default to
                    .Values.wait_for)
