[Offline pages] Creating BackgroundJobScheduler, which uses JobScheduler
In order to enable scheduling using JobScheduler, this patch:
* Refactors BackgroundScheduler to expose its functionality through
instance methods.
* Adds BackgroundScheduler#getInstance method to get appropriate
implementation of BackgroundScheduler (default uses GCM Network
Manager)
* Introduces BackgroundJobScheduler, which implements basic
scheduling using JobScheduler
* Updates TasksExtrasPacker to handle PersistableBundle, which
is required by JobScheduler (handling BaseBudnle would work if
min API level was 21).
* Updates/adds tests.
