Despite the effort the worker was not able to connect to the webui

Defaulted container "openqa-worker" out of: openqa-worker, wait-for-webui (init)

API key and secret are needed for the worker connecting openqa-webui:9529

As it turned out, that boiled down to openQA/lib/OpenQA/UserAgent.pm, which handles the case where the worker doesnt pass the keys in the command line. it seems that when the UA is initialized in some point gets those keys from the config files.
