RDB update PN doesn't use IPAM

[abarbare]

Hello,

When creating a rdb instance with a PN and IPAM, it works like expected, the config send to the API is using ipam_config flag.
When updating the PN id to a new one using another IPAM subnet, it seems to drop and recreate the instance endpoint but reusing the service_ip already defined with the previous configuration.
In case of update of a PN, we should check the client request and do not push the service_ip field if the client request an ipam_config.
service_ip is still necessary if the endpoint is configured with a service_ip (without ipam)

Thanks a lot,
