Make mask_dict_password case insensitive and add new patternsrocky-em3.36.5stable/rocky

In Icc19b7c8bdb6a3182939d5e9fdef21288b19f43d mask_password was made case
insensitive but mask_dict_password wasn't. This update makes the
behaviour of these functions the same.

Instead of lowering _SANITIZE_KEYS each time the source list is lowered.

New password patterns from realworld logs were added to the patterns.

+  - |
+    This patch ensures that we mask sensitive data when masking dicts, even if
+    the case doesn't match. This means the behaviour of mask_password and
+    mask_dict_password is now the same.
+  - |
+    Additional password names were included from real world logs that contained
+    sensitive information.
