add flavor provider

[Matt Fischer]

Nova is going to stop shipping with the default flavors, so we need a way with puppet to allow people to create their own flavors.

    Add nova flavor provider

    Nova is not including flavors by default anymore so there needs to be
    a way to create flavors with puppet. This change adds a nova_flavor
    provider for adding and removing flavors. Additionally the provider can
    be used to manage properties on flavors. Since flavor information cannot
    be updated after creation time, only the properties can be managed after
    creation via the nova_flavor provider.
