dask_scheduler with --dashboard-address [xx:xx:xx:xx:xx:xx:xx:xx] broken with IPv6?

**What happened:**
Using a IPv6 VM for dask, was unable to load the dashboard

user@host:~> python -m distributed.cli.dask_scheduler --host [xx:xx:xx:xx:xx:xx:xx:xx] --port 0 --dashboard-prefix /common_classify --dashboard-address [xx:xx:xx:xx:xx:xx:xx:xx]
