Detect deprecated decorators

[cdce8p]

Is your feature request related to a problem? Please describe

Pylint should be able to detect deprecated decorators, like abc.abstractclassmethod or abc.abstractstaticmethod.
https://docs.python.org/3/library/abc.html#abc.abstractclassmethod

Describe the solution you'd like

Emit a warning if a deprecated decorator is used. Optionally, suggest replacement.

Additional context

Implementation could be fairly similar to the existing checks for deprecated functions, classes and arguments.
