Since #27 vmware-go-kcl has support the any logger interface,
which is very nice.
However due to the fact that `logger/zap.go` directly imports zap.
zap became a dependency of whoever uses `vmware-go-kcl.` The
problem is that zap also has many dependencies.
In order to avoid KCL users to pay a cost for a feature they don't
need, the zap stuff has been moved to a `logger/zap` sub-package.
Fixes#45

* Add generic logger support
The current KCL has tight coupling with logrus and it causes
issue for customer to use different logging system such as zap log.
The issue has been opened via:
https://github.com/vmware/vmware-go-kcl/issues/27
This change is to created a logger interface be able to abstract
above logrus and zap log. It makes easy to add support for other
logging system in the fugure. The work is based on:
https://www.mountedthoughts.com/golang-logger-interface/
Some updates are made in order to make logging system easily
injectable and add more unit tests.
Tested against real kinesis and dyamodb as well.

* Add lumberjack configuration options to have fine grained control
Update the file log configuratio by adding most of luberjack
configuration to avoid hardcode default value. Let user to specify
the value because log retention and rotation are very important
for prod environment.
