dagster

I believe the import just needs to be switched to `from dagster.core.serdes import ConfigurableClass` in <https://github.com/dagster-io/dagster/blob/master/python_modules/libraries/dagster-cron/dagster_cron/cron_scheduler.py>

Are you running the same version for both `dagster` and `dagster-cron`?

I suspect that this is a version mismatch since the PR that changed the import from `dagster.core.serdes` -&gt; `dagster.serdes` also changed the location of the import in the  `dagster` package.

Just wanted to circle back, that change got everything working.  Thanks for the help!
