Consider making warnings PEP 565 compliant

See original GitHub issue

PEP 565, accepted in 3.7, redefined the semantics of several types of warnings. In particular:

For library and framework authors that want to ensure their API compatibility warnings are more reliably seen by their users, the recommendation is to use a custom warning class that derives from DeprecationWarning in Python 3.7+, and from FutureWarning in earlier versions.

Which means that AstropyDeprecationWarning is maybe not as visible as we think, and perhaps it should derive from FutureWarning in Python < 3.7.
