    Fix retry mechanism for generator results

    Both v1 and v2 of the glance client return python generators in some
    cases (rather than fully fleshed out lists) which thwarts our retry
    mechanism. Convert generator results to a list, so that any potential
    exceptions get raised earlier rather than later, allowing for retries.
