Prior to this change, (Context)SingletonBeanFactoryLocator used
BeanFactoryUtils#beanOfType(ListableBeanFactory, Class) to locate the
bean of type BeanFactory.
The more modern approach is to use BeanFactory#getBean(Class), which
removes a dependency on ListableBeanFactory interface while at the same
time opening the implementation up to respecting autowiring exclusions,
primary metadata, etc.

For consistency with all other constants representing default
property source names, such as
StandardServletEnvironment#SERVLET_CONTEXT_PROPERTY_SOURCE_NAME and
StandardEnvironment#SYSTEM_ENVIRONMENT_PROPERTY_SOURCE_NAME

Prior to this change, JndiPropertySource worked directly against a JNDI
Context instance as its 'source' object. This works well enough, but is
not nearly as fully-featured as Spring's existing JndiLocatorDelegate.
This change refactors JndiPropertySource from relying on an underlying
Context to relying on an underlying JndiLocatorDelegate. By default,
the delegate's "resourceRef" property is set to true, meaning that the
implementation will always try to prepand a given name with
"java:comp/env/" before looking up the name, and upon failure will drop
back to the given name sans prefix.
See JndiPropertySource Javadoc for complete details.
Issue: SPR-8490
Move JNDI_PROPERTY_SOURCE_ENABLED_FLAG from JndiPropertySource to
StandardServletEnvironment, as this is the only context in which the
constant makes sense.
Users may now work with command line arguments as a source of
properties for use with the PropertySource and Environment APIs.
An implementation based on the jopt library and a "simple"
implementation requiring no external libraries are are provided
out-of-the box.
See Javadoc for CommandLinePropertySource, JOptCommandLinePropertySource
and SimpleCommandLinePropertySource for details.
