We only want to render the account link and login items in the header.
And we want only render the Multitenancy and Administrators sections in
the admin sidebar.
We include the administrators management so it's possible to give
permissions to other users to manage tenants.
In order to restrict access to other sections by typing the URL or
following a link, we're only enabling the rest of the routes when we
aren't in the multitenancy management mode.
In order to the display a warn text on the last attempt
before the account is locked, we need update
config.paranoid to false as the devise documentation
explains.
Adding "config.paranoid: false" implies further changes
to the code, so for now we unncomment the default value
"config.last_attempt_warning = true" and update it to false.
