### problem
`enableStaticNat` starts failing just after several uses.
Actually I see that IP is assigned but the call still fails with timeout
just after 3-4 uses
For my test I created a number of VMs, and then tried to assign public IP to
all of them sequentially:
```
for i in `cloudstack listVirtualMachines | jq ".virtualmachine[].id"`
> do
> ip=`cloudstack associateIpAddress networkId=_my-network-id_ | jq
".ipaddress.id"`
> time cloudstack enableStaticNat ipaddressid=${ip} virtualmachineid=${i}
> done

I tried different configurations of network and VR, and got it always
failing, in the best case after 6-7 successful assignments.
large VR with 4 CPUS and several GB memory did not help neither.
`time` for all failing ones shows `real 0m10.350s` or slightly more.
Started from https://github.com/apache/cloudstack/discussions/10184
### versions
CloudStack 4.20.0.0 with
https://github.com/apache/cloudstack/pull/10254/files applied (PR does not help
with this)
Ubuntu 22.04.5 LTS
libvirt 8.0.0-1ubuntu7.10
isolated network over VLAN
about 1000 public IPs in /20
### The steps to reproduce the bug
1. Create number of VMs (I used 100, but looks like just several should be
enough
Repeat 2-3 for VMs in 1. till it starts failing (just after about 3-4 cycles
in my case)
2. Use `associateIpAddress` to get public IP ID
3. Use `enableStaticNat` with VM ID and IP ID
Initially `enableStaticNat` takes 9 seconds then increases to 10, and then
just starts failing with timeout
Here is a cycle doing the above
```
for i in `cloudstack listVirtualMachines | jq ".virtualmachine[].id"`; do
ip=`cloudstack associateIpAddress networkId=${YOUR-NETWORK-ID-HERE} | jq
".ipaddress.id"`
time cloudstack enableStaticNat ipaddressid=${ip} virtualmachineid=${i}
done
```
### What to do about it?
Looks like the call is taking too much time to return. Should be optimized.
