api support for sync job cancellation.

Fixes #2695

Description
Once a one-time or periodic sync job is canceled, it should emit the current sync job status. The cancel state, represented by the WorkInfo state, needs to be transformed into the current sync job status. This is done by listening to the WorkInfo state and mapping it to the current sync job status, using the WorkManager state for intermediate states and the FhirDataStore state for terminal states.

One way to do this is to accept ExistingWorkPolicy in sync apis. Instead of ExistingWorkPolicy.KEEP if application provides ExistingWorkPolicy.REPLACE, workmanager library will cancel the current one and add new one with the same name.

Why not the above approach ?

LGTM. Thanks Santosh.
