Add logout functionality using in memory context that clears token once user is logged out and no longer can be used for authorization

Working solution to security authorisation on api, handling endpoint requests as of roles student, teacher, admin. As of yet unit tests don't work and final functionality 'An admin can change the roles of other users'.

Add roles featuring student, teacher and admin rights using stateless jwt authorizations and build securiy filter chain to control access rights. No controllers set up as of yet.

Add rest api as controller of the app, refactor dto to entity mapping to be managed by MapStruct, move tests to seperate module and refactor them to be spring tests

Make project utilize spring-boot-data-jpa and mysql server as persistence layer
