Remove SingletonWithLifecycle, because @Singleton is not inherited

Remove SingletonWithLifecycle, because @Singleton is not inherited

and move @PostConstruct & @PreDestroy from interface Lifecycle to class
AbstractLifecycle, because method annotations are only inherited from
classes, not interfaces

Note that none of the annotations in question here have an @Inherited
annotation themselves.  For @PostConstruct & @PreDestroy it works anyway
with the blueprint-maven-plugin (I've now fully tested this end-to-end
in the netvirt aclservice-impl), and should be the same with Guice +
Mycila from what I can tell looking at that implementation.

Unrelated to above, this also fixes up the features.xml which I
originally forgot.
