Integrate OAuth into kotlin-reactive

[mraible]

@joshlong I tried upgrading all the dependencies to their latest releases, and integrating Spring Security OAuth into the edge-service project.

Unfortunately, the edge-service fails to compile after these changes. Any ideas?

[INFO] --- kotlin-maven-plugin:1.2.20:compile (compile) @ edge-service ---
[INFO] Applied plugin: 'spring'

Steps to reproduce:

git clone [email protected]:mraible/cloud-native-pwas.git
cd cloud-native-pwas/kotlin-reactive
git checkout reactive-oauth
cd edge-service
./mvnw spring-boot:run
