Masked error from Resource._validate_service_availability

[Rabi Mishra]

User gets to see "ResourceTypeUnavailable: Service heat does not have required endpoint in service catalog for the resource type OS::Heat::StructuredDeployment", where as the actual error is something else.

For example in the engine logs we have,

2016-02-01 10:53:24.233 11434 ERROR heat.engine.resource Forbidden: Trustee has no delegated roles. (Disable debug mode to suppress these details.) (HTTP 403) (Request-ID: req-2223404b-43da-467d-8482-b3ec73bb18f8)

    Don't mask exceptions in is_service_available

    We seem to be masking client exceptions when checking
    resource availability, it would be good to provide the
    proper error message to the user.
