Weld SE API - create convenient methods to specify SE-specific properties

Right now, Weld.property(String, Object) together with property name constant (such as Weld.ARCHIVE_ISOLATION_SYSTEM_PROPERTY) could be used, e.g.:

new Weld().property(Weld.ARCHIVE_ISOLATION_SYSTEM_PROPERTY, false);

This is error-prone and verbose. I think we should introduce convenient methods to switch from the default state, e.g.

new Weld().disableIsolation().enableDevMode().skipShutdownHook().scanClasspathEntries();
