Jetty 9.4.x 3755 annotation/jndi example cleanup (#3763) 

* Issue #3755 Annotation example cleanup

+ Created JettyDistribution class as common utility to locate a jetty distribution for examples.
+ Fixed ServerWithAnnotations to correctly use the test-spec-webapp
+ Added AttributeContainerMap as a better way to treat attribute values as beans. This avoids them appearing twice in a dump and always associates them with their key.
+ Added NamingDump and use it in EnvConfiguration and jetty-plus.xml so that a server dump will contain dumps of the server local tree and each contexts java:comp/env tree
+ Improved the dump format of NamingContext and WebAppContext
+ Improved the toString format of several associated classes
