Feature/graphql web UI (#649)

* Add "server" to "checkForUpdate" logic names

* Use "webUIRoot" as default path for "getLocalVersion"

* Use local version as default version for "isUpdateAvailable"

* Return the version with the webUI update check

* Update WebinterfaceManager to be async

* Add query, mutation and subscription for webUI update

* Catch error and return default error value for missing local WebUI version
