Automatic update of OverviewPage after post-confirmation user interaction in CreationPage

[Torgeir333]

Description

The OverviewPage is now automatically updated (from Redux State)
after a new user interaction step has been added in CreationPage.

After clicking confirm/Opprett, the user gets a confirmation
(and the new POST id return update, see Issue8) upon a successful
creation of a new SystemUser (in both BFF, Real Backend etc...)

When he clicks the OK button, the state of the CreationPage is reset,
a GET request to BFF for an update OverviewPage list is sent,
and the user transferred to the OverviewPage.

The BrowserBackButton scenario will be dealt with in a future iteration.

Design for the new user interaction is not in yet.
