[tapocontrol] Move error messages to i18n

[wildcs]

before this pr error messages were declared as constant.
moved them to i18n

Your approach looks strange. If you want to provide generic messages with a number as parameter, you do not need to duplicate entries to be translated. Create one with a parameter, something like received error code ({0})

[lolodomo]

And your way to retrieve the constant name to get the i18n entry is not very good.
Why not simply create an enum type containing all your errors ? Then you just have to retrieve the enum name from an int value.
Something like (partial code):

enum TapoError {
    ERR_API_COMMON_FAILED(-1),
    ERR_API_SESSION_TIMEOUT(9999),

...

    int code;
   TapoError(int code) {
       this.ocde = code;
    }

    static TapoError fromCode(int code) throws xxx {
        ...
    }
}

Then your i18n entry can be built using TapoError.fromCode(code).name().replaceFirst("ERR_", "error-").replace("_", "-").toLowerCase()

Thanks for your hint. Changed it and hope it's okay now.

Looks clearly better.
