Detect and handle when gRPC get-results timeout is shorter than ConServ's estimated job duration

[BatmanAoD]

The gRPC API now has a way to get the "estimated delay" before a job will be complete: https://docs.api.qcs.rigetti.com/protobuf/#services.controller.EstimatedDelay

When the minimum delay is greater than the get-results gRPC timeout, the client will not be able to get the job results.

The SDK should automatically detect this situation (by requesting the job status either immediately after submitting a job, or automatically as part of requesting the job results), and it should permit the user to do either of the following:

• cancel the job
• re-request results with a sufficiently long timeout
