Tg 11 single docker compose

[KaiserZoza]

Updated docker compose file and renamed related files to properly represent the new behavior.
Docker compose now does the following:

1. Fetches Keycloak image
2. sets Keycloak variables
3. starts Keycloak development environment
4. imports realm from json
5. builds dotnet application
   1. fetch dotnet sdk image
   2. install npm
   3. restore packages
   4. publish application
   5. set entrypoint
6. create network
7. join both containers into the same network
