Wekzeug library cached_property changed its namespace since version 1…

[erodrig]

Starting from werkzeug version 1, the cached_property class has been relocated from here, in which it was flag already as deprecated: https://github.com/pallets/werkzeug/blob/0.16.x/src/werkzeug/init.py

into here:

https://github.com/pallets/werkzeug/blob/master/src/werkzeug/utils.py

In order to prevent issues in projects still using older versions of the library I am using a conditional import.
