Use a System property to define bundles that contain tlds that need to
be treated by jasper as if they were on the jetty container's classpath.
The value of the property is evaluated against the DeploymentManager
context attribute "org.eclipse.jetty.server.webapp.containerIncludeBundlePattern",
which defines a pattern of matching bundle names.
The bundle locations are converted to URLs for jasper's use.
Comma separated list of names of bundles that contain tld files that should be
discoved by jasper as if they were on the container's classpath.
