Removes limitations from Dask dependencies (#22017)
Dask dependencies were holding us back - when it comes to upgrading
somoe of the packages (for example apache-beam and looker - in google
provider). This PR removes the limitations but with a twist.
* Dask tests stop working. We reach out to the Dask Team to fix them
but since a very old version of `distributed` library was used
the Dask team is called for help to fix those
* The typing-extensions library was limited by `distributed` but it
seems that version 4.0.0+ breaks kubernetes tests
