Bug Description
Use case to solve: as an operator I want to expand or shrink Public network without re-allocating all Floating IPs.
Currently, updating subnet CIDR is blocked by validation from API side. By the way, PD code is already updating CIDRs so far.
Generic approach is:
1. Accept CIDR and optionally allocation pools and gateway_ip.
2. If new allocation pool is not provided, and old pool is not fit into
CIDR, then fail. Same for GW.
3. Re-allocate IP if they're out of new allocation pool.
Here is a proposed patch https:/

What is your use case? Usually there are good reasons for making certain resources immutable, like the CIDR on a subnet.
