Return boolean result of put() in AbstractKinesisRecorder.saveRecord()

[tylerjroach]

Which AWS Services is the feature request for?
Kinesis Codegen

Describe the solution you'd like
AbstractKinesisRecorder.saveRecord() should return success boolean to inform if the save completed successfully.

** Current Workaround**
AbstractKinesisRecorder provides getDiskBytesUsed() which can be used to detect when the record store is getting close to the limit by comparing it with config.getMaxStorageSize().
