This upgrade takes care of our move to JDK 17, Spring Boot 3.0.1 and a
few other security upgrades along the way.
Fixes#18993
TODO:
- [x] Check CI changes for Java 17
- [x] Check vulnerability report
- [x] Mongock needs an upgrade
- [x] Add JVM args at all possible places for exposing java.time module
- [x] Add type adapters everywhere / use the same config for type
adapters everywhere
We are moving to a multi-module structure so that different parts of the codebase can be exposed to the public while others can remain private. Using pf4j for plugin framework.
Also adding a build script `build.sh` which compiles the code and creates the `dist` folder for distribution purposes. Now we can build the code via
```
$ ./build.sh -DskipTests
```
