Add memory circuit breaker #303

I'd like to add memory circuit breaker on LTR memory usage to not impact the cluster availability, like ingestion function, when the system memory usage is high.

This seems like a smart thing to do, what would be the behavior when memory usage is too high?

jngz-es commented 4 years ago

What I am thinking is rejecting APIs which consume memory like create model/feature set etc.
