Feature/gateway

[DMurf]

Description

This feature will implement a control on the use of the Schools Profile website, ensuring that a finite number of users can "register" and have a look around.
The registration process is simply a capture of email, with a parameter in the URL for which local authority they were referred from. This is to help with user research and understand what the service can provide for the public.

Once registered, users will receive an email with a link to return at a later date, but no longer than 7 days. The 7 day limit is enforced from a KeyVault value and can be changed.

The emails are stored in postgres, as are the Local Auths. There is also an instant kill-switch in the settings sql table should there be a need to close the application.

On every page load the gateway middleware checks for a cookie that matches a user's id, and if expired will direct them to the appropriate page.
