Add proto support for the new registeredIPAddresses feature, which lets a
caller mark specific IPs as reserved in IPAM without allocating them to a
NIC/LB. The reserved IPs are persisted on each IPPool and survive
restarts.
Proto changes:
- rpc/common/moc_common_networkcommon.proto:
- IPPool.registeredIPAddresses (field 7): per-pool list of registered IPs
(storage layer; rehydration loops directly without re-running pool
range-routing).
- IPUpdateErrorCode enum: per-IP failure codes
(UNKNOWN, INVALID_FORMAT, OUT_OF_RANGE, SUBNET_NOT_FOUND,
ALREADY_ALLOCATED, NO_POOLS_IN_SUBNET).
- IPAddressUpdateFailure message: { SubnetName, IPAddress, Code, Error }.
- rpc/cloudagent/network/{logicalnetwork,virtualnetwork}/*.proto:
- UpdateRegisteredIPs RPC.
- {Logical,Virtual}NetworkIPUpdateRequest / Response.
- {Logical,Virtual}SubnetIPUpdate { SubnetName, RegisteredIPAddresses[] }
(subnet-scoped flat list; cloudagent routes IPs to pools by range).
The dual layer (subnet-scoped on the wire, per-pool in storage) keeps the
RPC ergonomic while making rehydration cheap and self-describing.

The Error field on LogicalNetworkIPUpdateResponse and VirtualNetworkIPUpdateResponse was never reachable on the wire: the cloudagent only set it together with a non-OK gRPC status, and gRPC clients discard the response body on non-OK status. Document Failures as the per-IP failure channel and the gRPC status as the whole-batch failure channel; regenerate the .pb.go files.
