Cannot configure multiple Glance stores

[Mathieu Gagné]

You can't have multiple glance stores configured with puppet-glance or you get duplicated default_store glance_api_config resources.

The default_store config should be moved to glance-api and a logic implement here to auto-detect its value:
- If only one store is configured, use that one as default. (keeping default behavior)
- If multiple stores are configured, require the default_store value to be provided.

We should also rename "known_stores" parameter for "stores" to be consistent with the new config name: glance_store/stores.

    Implement multiple store configuration

    This patch moves the default_store config option to the glance::api
    class, and makes it possible to configure more than one store while
    supplying a value for the default store to be used. If only one store
    is given for glance_store/stores, the default store is automatically
    set to be the same value. If multiple stores are given and no default
    store is explicitly set, the config will fail and ask the user to
    provide a default store.
