Support overriding Zookeeper connector to production via env property

This will allow to run production connector (and no stub runner) without `prod` profile (e.g. under `dev`) if `microservice.production` is defined
We have the https://github.com/4finance/micro-infra-spring/blob/master/micro-infra-spring-base/src/main/groovy/com/ofg/infrastructure/environment/EnvironmentSetupVerifier.groovy that should check that a profile has been passed so you should not have a case that not a single profile has been provided.

Also we try to approach the case of profiles in a very simple way - it's either prod / dev / test. Anything outside of it is a customization that we can't forsee. What do you think about this?
