Builds off of PR ( dask/dask#9087 )

This function was refactored out in Dask and still has the same functionality. While initialize_worker_process does work, it does a bit more than is needed (taking a UDF to initialize too). So just use default_initializer.

Also there is no need to handle old Dask versions here since we now pin Dask & Distributed to the exact same version. So drop the fallback code.
