First end to end test with simple scenario with no introduced errors.

+ PoolProviderListener for feedback on the pool.
+ User object capability on lease requests so when they become fully asynchronous later on users will have some home of aligning lease requests with leases granted, user objects are passive within the pool.
+ Test utilities, a Simple betty based server.

Take a look at NettyConnectionPoolBuilderTest for an example of how it will probably be structured.
