Describe your issue.

Since SciPy 1.8.0, importing ODEintWarning from scipy.integrate.odepack raises the following warning:

DeprecationWarning: Please use ODEintWarning from the scipy.integrate namespace, the scipy.integrate.odepack namespace is deprecated.

However, importing ODEintWarning from scipy.integrate fails. I think the solution is to add ODEintWarning to scipy.integrate._odepack_py.__all__, but I want to check if I'm misunderstanding something obvious before I attempt a PR.

Reproducing Code Example

from scipy.integrate import ODEintWarning

Error message

ImportError: cannot import name 'ODEintWarning' from 'scipy.integrate' (C:\Anaconda3\lib\site-packages\scipy\integrate\__init__.py)
