Disable saving (tensorboard) log files

[Lucaweihs]

Problem

We should be able to disable tensorboard logging from the command line. We also need the option to skip other type of logging (e.g. saving to the used_configs folder).

Solution

Hopefully this is as easy as passing a few additional parameters to the runner.

Dependencies

None

I just added two options (-i to disable tensorboard logging, -a to disable saving the used configs).
Currently, I still let the inference engine collect visualization data if a visualizer is present in machine params, but I could avoid it by passing a flag from runner if that's not sufficiently efficient...
