* Fixing possible race condition when passing backoff around as a pointer.
* Adding a debug logger that is turned off by default.
Info logger is enabled by default but prints out less information.
* Removing OK Aurora acknowledgment.
* Making Mutex a pointer so that there's no chance it can accidentally be copied.
* Changing %v to %+v for composite structs. Removing a repetitive statement for the Aurora return code.
* Removing another superflous debug statement.
* Removing a leftover helper function from before we changed how we configured the client.
* Changing the logging paradigm to only require a single logger. All logging will be disabled by default. If debug is enabled, and a logger has not been set, the library will default to printing all logging (INFO and DEBUG) to the stdout.
* Minor changes to demonstrate how a logger can be used in conjunction to debug mode.
* Removing port override as it is not needed
* Changing code comments to reflect getting rid of port override.
* Adding port override back in.
* Bug fix: Logger was being set to NOOP despite no logger being provided when debug mode is turned on.
* Turn on logging by default.
* Removing option to override schema and ports for information found on Zookeeper.
* Turning off debug mode for tests because it's too verbose. Making sure LevelLogger is initialized correctly under all scenarios.
* Removing override fields for zk config.
* Remove space.
* Removing info that is now incorrect about zk options.
* Fixing possible race condition when passing backoff around as a pointer.
* Adding a debug logger that is turned off by default. If debug is turned on, but a logger has not been assigned, a default logger that will print to STDOUT will be created.
* Making Mutex a pointer so that there's no chance it can accidentally be copied.
* Removing a leftover helper function from before we changed how we configured the client.
* Minor changes to demonstrate how a logger can be used in conjunction to debug mode in the sample client.
* fixed semantics. Earlier mentioned that 'Pystachio does yet support...'. Changed now to mention 'Pystachio does not yet support...'
* fixed grammatical mistake.
* Ran gofmt on project.
