Promote deprecation warnings to future warnings

[maximlt]

This concerns all the deprecated features listed in the table below. Then we release (2.1.2 or 2.2.0), remove in the next minor release (2.2.0 or 2.3.0), with a couple months between the two releases. The last two deprecations at the end of the table may need more time before removal as they were more recently promoted to ParamDeprecationWarning (in 2.1.0 in March of this year).

I think we should update the warning in the next minor release, 2.2.0.

Agree, let's make the next release 2.2.0.
