Oc client limited retries

[pbazydlo]

Resolves: #136
Doesn't do exponential backoff.

• Please verify if configuration params make sense.
• When number of retries is exceeded nice error is shown and client stops retrying.
• Retries are counted per component href.

in test/front-end/ocTestConfig.js i set oc.conf.retryInterval = 1 so that retries happen very fast and can be reasonably tested, this is hooked up in test/configuration/karma-local.js so that the config is set before oc-client is loaded. it worked when running grunt test and grunt karma:local but it seems i missed something

[pbazydlo]

i pulled common configuration from karma-local and karma-sauce into a separate file

@matteofigus passing now, as for running karma:sauce locally we could add karma:sauce-local task and install chrome driver, then we would be able to run it locally
