---------------------------+---------------------------------
A `cached_method`'s `clear_cache()` clears the entire dictionary of a
`cached_method`. Currently, there is no way to only remove some keys. This
is sometimes necessary if values in the cache are not usable anymore (e.g.
because they are defined in some external expect interface but the
external session is not running anymore, #16369).
This tickets adds an optional parameter to `clear_cache()` which removes
only the specified keys from the dictionary.
