Create Volume dialog - No helper text for Type, and no guidance on how to create one

[Matt]

When you create a Volume, and you don't have a Type defined, there's nothing in the dropdown. While it's empty, and not marked as required, it still makes me a little nervous and wonder what I'm missing out on by not having a Type to pick. Many other dropdowns in OpenStack either have a default value, or some helper text instead of just being empty. The Launch Instance dialog has "--- Select source ---" for Instance Boot Source, and on the Access & Security tab, if you don't have any Key Pairs, it says "No key pairs available, with a + button you can click that takes you to the Import Key Pair dialog.

I'm honestly not sure how important Type is, especially since you can't seem to do much with it in the UI yet, and have to use the CLI to actually configure more than a Name for it, but it seems like there should be some helper text or a string that says they don't have one yet, and possibly help link them over to where they could create one.

    Add text to the Create Volume dialog's Type menu

    The first value in the "Type" dropdown menu of the Create Volume dialog
    was empty. This causes some confusion to the user because there was not
    enough information as to why the value was empty or what would happen
    when creating a volume with the empty type.

    Adding text "No volume type" to the first value of the dropdown menu
    explains that there will be no volume type associated with the volume
    at creation time.
