Before this commit, the AutomaticJobRegistrar was started on
ContextRefreshedEvent event. This is sometimes too late to register jobs
especially when other life cycle components that use the jobs are started
before this registrar.
This commit changes the AutomaticJobRegistrar to implement SmartLifeCycle
and makes its autoStartup and phase properties configurable.
It should be noted that the "onApplicationEvent" method has been removed
even if it is a public API. This method is not intended to be used by
client code and even if it was, its usage is considered wrong anyway.
