* @param {Number} [settings.discoveryRetryDelay] the minimum delay between two arbitration retries
* @param {Function} [settings.arbitrationStrategy] Strategy for choosing the appropriate provider from the list returned by the capabilities directory with the function signature "function(CapabilityInfos[])" that returns an array of CapabilityInfos
* @param {Number} [settings.cacheMaxAge] Maximum age of entries in the localCapabilitiesDirectory. If this value filters out all entries of the local capabilities directory a lookup in the global capabilitiesDirectory will take place.
