Description

Working on ACCUMULO-4050, I've realized that there's a bunch of simplifications we can do to the existing AccumuloConfiguration and related objects. These are generally lots of small refactorings, but there's sufficient cleanup that I need to do it separately from ACCUMULO-4050, otherwise it's going to overhwelm me and I'm never going to finish that issue.

Specific things include:

• Remove redundant ways to get the default config
• Move static type converter method clutter from the AccumuloConfiguration API (to separate class)
• Streamline default config construction with stream syntax
• Simplify internal predicates for filtering properties with lambdas
• Rename ServerConfigurationFactory.getConfiguration() so it reflects that it is the system config
