WIP: Initial CoreLogger implementation

Created MR from forked repo until I get access.

Initial CoreLogger implementation for review. Only the info methods are added for an example.

Example usage would be something like:

CoreLogger logger = CoreLoggerFactory.getLogger(SomeClass.class);
logger.info("Log this message");

ICoreLogger. An interface that supports collecting information about services and dependencies to meet observability/monitoring requirements.

Generally, this interface should support logging traces, events, dependencies, and exceptions so that a dashboard can show: 1) availability, 2) exception rate and failures, 3) performance counters, 4) dependency among services.
