Comments related to the REST part

Compared to what we did in the class I have added an alternative version of PUT on:

\api\Customers\V2\{id}

I prefer the version that reports a non-existing Customer as an error, but remember you are free to create IF you return 201 in those cases

Comments related to the Documentation part

• This version provides swagger generated documentation on: http://localhost:8080/swagger-ui/index.html#/
• All it took to get this was:
  • the springfox-boot-starter dependency in the POM-file
  • the SwaggerConfig class in configurations
