This changes adds resource name matching to the trace sampling rules.

This change also changes matching on service and operation name to use glob matching -- which does introduce a small breaking change if someone used * or ? in their name previously

In addition to the core change to trace sampling rules, this code also cleans up the handling of glob matching

New util classes Matcher and Matchers have now been introduced that handle most of the glob related code

This clean-up allowed me to eliminate some existing duplication in the single span code

In a subsequent changeset, I may replace the pattern based glob matching with a proper glob matcher.
