Add the ability to display a cluster "name" on the Dashboard status page

[orf]

If you are launching different Dask clusters and viewing the cluster information in a dashboard it can be hard to correlate a given dashboard to a job.

It would be great to be able to display a custom string somewhere on the dashboard to identify this. For example we currently hard-code the title of the scheduler status page to Dask: Status here (

distributed/distributed/dashboard/components/scheduler.py

Line 3488 in 8d0df89

doc.title = "Dask: Status"

). Being able to add a custom prefix or suffix would help, or alternatively display a panel below the navigation toolbar.
