Hotfixes cherry pick
Providers listing is no longer stored in lists, it's now driver dict based.
Updated `is_provider_configured` to look for data in the new dict based providers config.
Minor typo.
Let us know what's going on when an exception happens on parallel querying nodes.
Pass current opts dictionary to `vm_profiles_config` and `cloud_providers_config`. This will help unifying profiles with providers.
ALL configuration parsing, merging and unification is now done in `saltcloud.config`.
One step further. Refs #546

* All cloud profile now has it's provider set as `<alias>:<driver>`. This is done when loading the configuration.
* All cloud providers settings now include a `profiles` key for each of it's driver which included every profile that is using the `<alias>:<driver>`. This is done when loading the configuration.
* Cloud profiles are no longer stored as `vm` in the internal configuration dictionary. It's `profiles` now.
* Fixed the `ec2` driver because of how the data is laid out now.
* Fixed the `get_config_value` config helper, also because of how data is laid out now.
