DM: failure to canary a sink is now fatal.

This requires we remove NVPR from the default set of configs, as we only find
out at runtime that it's not available.  All the other defaults will either be
compiled in and supported, or not compiled in and non-fatally skipped as
unknown configs.

LGTM.  I suspect we'll see lots of failures from this.  May want to warn the
sheriff.

Thanks for the warning; I'm out of training and will come watch the tree burn.
