Grid Manager: consider disallowing downloads as well

Launchpad Bug:


The Grid Manager addresses one aspect of managing a grid: rejecting clients that have access to the grid from also offering storage. The implementation currently will use any server at all for download shares (if they have them). This is safe, because we check the (hash of the) ciphertext even before decrypting it and it might increase availability.

During code review, it was pointed out that perhaps it might be worth considering a mode for the grid-manager to reject downloads (or probably simply all operations) except with "blessed" nodes (that is, nodes a grid-manager has issued a still-valid certificate for).
