feat: example use Ory Hydra. Spring Boot 2 (Java 11), Angular, Docker (Docker Compose)

[Chistousov]

Hello Dear Ory Hydra Developers

Please add my project as an example of working with Ory Hydra.
The project was developed using Spring Boot 2 (Java 11), Angular, Docker (Docker Compose).
The project aims to take a broader look at authentication and authorization using OAuth 2.0.
There is no business logic as such here.

Thank you for your great Ory Hydra project.
Ory Hydra helped me implement flexible internal authentication and authorization within the company.

Ready to modify and correct the project!
