Set development mode and activate all debug logs

[brunomacf]

At now all logs are disabled by default and this is no satisfactory for work with vamp-docker-images as a development environment for all vamp components. Consider to add a flag to sinalize development mode and activate all debug logs.

@brunomacf is this specifically for the QuickStart package?

[brunomacf]

@olafmol I don't think so, since we can run clique-* packages independently i think we should implement this strategy in each package. By the way, since quickstart is build upon other clique-* modules it will inherit from it. What do you think? Did i understand you right?

i think it makes a lot of sense to have a single flag to enable/disable logging for all components. 👍

Me too... but consider this: mesos logs for example are disabled in clique-zookeeper-marathon image and quickstart module inherits from it. So, to enable logging through a DEV flag we should script this up in clique-zookeeper-marathon and then this will be available in quickstart image. The same is true for elasticsearch logs which are disabled (i.e., only error logs) in clique-base image and all other images inherits from it.
