Add favicon for ntnu and loginpage

Stop copying node_modules into frontend image

See merge request !331

Add english responsible text

See merge request !330

By not having a .dockerignore file we are including the node_modules
directory in the frontend image, and then installing all the packages a
second time in the build phase when we run npm ci. We now let npm ci do
that work as it's supposed to.

New footer and upper case name ntnu

See merge request !329

Move end role notifications to day after end

See merge request !328

By moving the notifications to midnight on the day they expire we
simplify the work of systems integrating with greg. The frontend has
also been updated to say that end dates are "to (including)" to clarify
that the roles are valid on their last day.

Notify sponsors of bad emails in sent invites

See merge request !326

Add NTNU design for their domain

See merge request !327

Introduces the invalid field on the Identity model. The field is used to
indicate that the Identity is in invalid. This is useful when a value is
not a working value, even though the value passes validation checks,
like unused national id numbers, emails tied to non-existing domains,
etc.

Resolves: GREG-252

If the sponsor writes a valid but non-existent email in a guest invite
we retried sending this email indefinitely. Instead of leaving django q
in an endless loop, we now send an email to the sponsor warning about
the problem instead.

Prepare for guest migration

See merge request !322

If an identity already exists in greg, but is tied to a different
person, we tried to add it, causing an integrity error. We now check if
the value already exists. If it is tied to the person we are adding info
for, we simply update it. Otherwise we skip this value.

Show orgreg_id instead og id after ouUnit

See merge request !321

Introduces the new identity type migration id, meant to be used when
migrating a person from another system.

The cerebrum guest import script has been expanded to use this new
migration id. The script has also gotten an option to import people
without the necessary IDs (NIN/Passport) so that we can generate IDs for
them in GREG. The can then be imported by cerebrum manually before we
add the remaning info from a different source. In this case we use old
info from UiO SAP.

GREG-247: Make the org unit list sorted alphabetically in the admin interface

See merge request !318

Make import_guests command more lenient on source

See merge request !319

The database constraint on the Identity model demands only one value per
id type for each person. This means that a person with a pass number
already in greg from a different source than the one we are trying to
import will trigger an integrity error when we try to create it.

The logic now instead checks for identities with other sources as well,
and if a match is found from another source system, the source is
updated to the one in the data we are importing. This will also mean
that a previously entered manual entry, will be converted to one marked
as automatic.
