Title: Initial version of new java client for prometheus.

This is based on the existing client, with the following changes:
- No external dependencies in core client
- Number of labels is fixed
- Initilises to 0 when there's no labels
- Convenience methods for no labels
- Support for multiple registries
- Only supports text output format

This code is MVP, there's no validation of metric or label names,
AtomicDouble would be better in Counter/Gauge and I'm sure there's a better
way to architect all this class wise (the api is a bit text format specific
for Summary for example).
