log time delay of domain setup in info level (#7808)

Browse Source 
* log time delay of domain setup in info level

 * when setup problems appear, it's difficult to debug which are the components that took a lot to set up. This minimal change goes further than the 'slow setup warning' and measures the setup time interval for each domain.

* use timer as in helpers/entity
