Query for storage profile href rather than include

First pass. Works. Includes a unit test that tests very little.
Existing integration tests still work. No new ones added, yet.
Raise error if the storage profile is not found

I haven't raised an error if the VDC isn't found - if the VDC isn't found at this point we've got bigger problems. Needs some thought as to how to address them.
We no longer need to pass the href

So this should just check that the correct storage profile has been assigned.
Add a specific integration test for SP

This requires a lot of specific set up, so I have excluded it from the integration test rake task but I have included instructions on what is required to set it up and run it if you wish to do so.
Add test to confirm that no SP = default

If you do not specify a named Storage Profile, it will default to whatever the default storage profile is in your vDC. This test clarifies that.
When a SP doesn't exist, default SP is used

This is the case where you specify the name of a storage profile but that SP does not exist. In this case, the VM also uses the default. This test clarifies that.
Remove href from example input
No longer require a hash for storage profile

Since we no longer need to provide the href to add a storage profile, we do not need the data to be a hash.

Previously, it was:

    storage_profile:
      name: name
      href: href

Now it can be:

    storage_profile: name

There is a bug in vm_orchestrator

If one part of the provisioning fails it raises an error but leaves the VM in a half-provisioned state. I have created tests that demonstrate this and will raise a bug in Pivotal as this goes beyond this story.
Use anchors instead of repeating data
Version bump

The change is backwards incompatible.
Bump minor version instead

Point 4, here: http://semver.org/ - We are still in development and the public API is not stable.
