    Add "normal", optparse-style options to swift-ring-builder add.
    
    The old format is still present and works just like it did before, so
    your existing scripts won't break.
    
    New format pros:
     * it's readable even for Swift newcomers
     * it's easy to extend
     * it's familiar to anyone who's used a Unix command line
     * we don't have to maintain the parser
    
    New format cons:
     * you can't add multiple devices in one go
    
    Old format pros:
     * you can add many devices with one command
     * it's compact
    
    Old format cons:
     * it confuses newcomers
     * "wait, is that zone dash IP colon port slash device, or zone slash
       IP dash port colon meta underscore device?" Just try walking
       someone through adding a device over voice chat.
     * it's annoying to add new fields
    
    Note that this only affects the command "swift-ring-builder
    <builderfile> add". Other swift-ring-builder commands are unchanged.
