Lukso-3 Add UI for keyexchange

[AlexNi245]

If a new device controller log into the UP, the client has to start the KeyExchange process to distribute the new keys to the new controller

• When logged in with the new controller. The user has to get instructions on how to execute the KeyExchange with an already connected controller
• The client has to detect an ongoing keyExchange process and let the user update the KeyStore if an oldController is connected

[AlexNi245]

The user can experience 5 different states when login in with lukso. We need a UI for each of them.

NEW

The UP has never used DM3 before. The user has to create profileKeys and publish them onchain

CONTROLLER_KNOWN

The UP has used Dm3 before, and the keyStore has been published. Hence the user can just login.

CONTROLLER_UNKNOWN

The Up has used Dm3 before but with a different controller. To use it with the current controller it has to publish its publicKey to the KeyStore, so another controller can share its public Keys with them

OPEN_KEY_EXCHANGE_REQUEST

The UP is connected to a controller which already obtains the profileKeys but it has noticed that another controller wants to exchange the profileKeys after the step CONTROLLER_UNKNOWN. It has to execute the keyStoreExchange

KEY_EXCHANGE_PENDING

The controller has completed all steps of CONTROLLER_UNKNOWN. It has to wait until OPEN_KEY_EXCHANGE_REQUEST has been exectued
