DEPR: Pandas 0.24.0 Deprecations
We'd like to have all these deprecations in place for 0.24.0, and enforced in 1.0

As a reminder, the plan is to have no new deprecations in 0.25.x and 1.0.0. So this is the last round of deprecations before 1.0.

- [ ] `Series.rename(scalar)` -> `Series.set_name` (xref https://github.com/pandas-dev/pandas/issues/14829)
- [ ] `NDFrame.filter`
- [ ] `NDFrame.between`? (https://github.com/pandas-dev/pandas/issues/13027)
