[W] disallowed_warnings

Sets the criteria used to identify deprecation messages which should be disallowed. Can be an array containing strings, symbols, or regular expressions. (Symbols are treated as strings.) These are compared against the text of the generated deprecation warning.

Additionally the scalar symbol :all may be used to treat all deprecations as disallowed.

Deprecations matching a substring or regular expression will be handled using the configured Behavior#disallowed_behavior rather than Behavior#behavior.
