This PR specifies preconditions for installing canister code via the corresponding management canister endpoints that must be satisfied (if provided) for the call to succeed. The motivation is to prevent canisters that are not stopped from being installed and to enable compare-and-swap semantics for installing canisters (by atomically "comparing" the canister history before "swapping" the canister code).
