+#   1. find all the go files; (exclude specific path: vendor etc)
+#   2. find all the files containing specific tags in contents;
+#   3. extract related dirs;
+#   4. remove duplicated paths;
+#   5. replace . with ${PRJ_PREFIX}
+#   6. merge all dirs in array with delimiter ,;
+#
+# Example:
+#   find_dirs_containing_comment_tags("+k8s:")
+# Return:
+#   sigs.k8s.io/descheduler/a,sigs.k8s.io/descheduler/b,sigs.k8s.io/descheduler/c
