feat(service): Add vehicle consumption service which receives POST request and returns its co2 emissions or kwh consumption per m

[lierseleow]

The merge request includes:

• The REST service using springboot
• simple unittests for the Endpoints
• A config loader that loads vehicle information using .toml files
• simple unittests for the config loader
• A Dockerfile to build a container for the service

The REST Service has only boilerplate for Exception Handling and CORS configuration, no specific implementations / config.

The REST Service provides /status Endpoints to monitor the current status of the service. The REST Service provides /v1 Endpoints to access its resources.

To access vehicles use /v1/consumption with a POST request and the following data:

{
    "vehicle_name":"car"
}

An example curl command is in README file of the service. For curl you will need to escape any double quotes with a backslash (\").

The /status/alive and /status/ready currently return OK on the same conditions.

TODOs:

• [x] Implement proper ready conditions for ready endpoint
• [x] Add Request validation
• [x] Add more information to the README file
• [x] Add comments to code
