This implementation is similar to the implementation in the hcloud-go. To give the "user" as much as verbosity as possible i introduced two methods.
validate
which is a simple validator that just returns True/Falsevalidate_verbose
which also returns the corresponding error message (like which key/value is not correctly formatted)I decided against calling one of both function in the other and instead duplicate the code. This is based on my feeling that the code would be more complex when we as a sample call validate_verbose in validate. Also, it is slightly more readable imho, but we can discuss this :)
Closes #153
