Currently the only option to test for processor readines is
WaitForReady
method.This method is blocking until processor is ready.
When processor is dealing with long initialization, this call becomes unresponsive for virtually indefinite time. This behaviour is deal breaker for monitoring calls that just want to check on the status of the processor and return in reasonable amount of time i.e. Kubernetes healthcheck.
This change adds context aware method
WaitForReadyContext
that has all the same checks with addition to context cancelation check. This allows it to return when context is canceled with the context reported error. If the error is not nil it indicates that processor is not ready.
