Authentation: Persist the login token temporarily

[SchoolGuy]

Is your feature request related to a problem? Please describe.

As a developer
I want to not login after every hot reload
so that I don't have to navigate to the page under development every time.

Describe the solution you'd like

As I am not very savvy in web security I have not saved the login token anywhere. This causes the Web Interface to be unauthorized every time a page is reloaded. I am sure that there is a somewhat secure way to get this saved temporarily.

The token lifetime can be retrieved via the settings attribute auth_token_expiration. Every successful request where a token is validated successfully will reset the timeout. As such only a token that is unused for the expiration time will be removed. Tokens will also be invalidated in case the backend is restarted.

Describe alternatives you've considered
