Add blueprint schema fetch if catalog version not available

[an2ane]

This was done because if a catalog item version is no longer available, the update function returns a 404 error. However, the blueprint version still exists and contains all the useful information we need to update a deployment.

We had an issue where an already deployment resource where no longer terraform compliant if a catalog item version was no longer available.
