Custom Scheduler

I'm looking into writing my own custom scheduler for Dask. I couldn't find a similar issue on github.

As far as my knowledge goes, there is only support for the default Scheduler, provided by Dask, as my (superficial) view through the codebase seemed to point out that the Scheduler class was hardcoded and not dynamically loaded.

Could I be informed if this assumption is correct, what the best way to go ahead would be if it is, or how I should implement a custom scheduler if the assumption is wrong?

Thanks in advance!
