Added subview for polling configuration in system configuration window

* updated architectural concept os subview
** added base class BaseConfigurationView
** updated interface ConfigurationGroup
* updated message strings for new pollign configurations
* implemented new vaadin compontent DurationField (extends DateTimeField)

TODO:
* update positioning of DurationFields
* update validation of user input, espacilly against min and max value
