Feature: For `StaticResourceJobCoordinator`, trigger job restart when input stream partition count changes or input stream regex set changes. Changes: 1. Add pluggable `JobRestartSignal` interface for triggering a job restart. 2. Add `StreamPartitionCountMonitor` and `StreamRegexMonitor` to `StaticResourceJobCoordinator` for triggering a `JobRestartSignal` when input stream partition count changes or input stream regex set changes. Tests: Added some code into `StreamPartitionCountMonitor` which triggered the callback after 5 minutes and verified that the placeholder `NoOpJobRestartSignal` was called. API changes (all backwards compatible): Configure `job.coordinator.restart.signal.factory` to specify an implementation of `JobRestartSignalFactory` to use. -- This is an automated message from the Apache Git Service.
