test_mm_domain_limits fails intermittently due to unhandled memory resource limit error (errorCode 535)

### problem

While working on PR #13490, I noticed the Simulator CI / test job intermittently fails on test_mm_domain_limits (test_03_delete_vm).

The test calls deployVirtualMachine, which fails with CloudStack API errorCode 535: "Maximum amount of resources of Type = 'memory' ... is exceeded". Because the VM was never created, the test then attempts to delete a VM that doesn't exist, causing test_03_delete_vm to fail.

The test does not currently handle this resource-limit API error as a valid/expected outcome.

### versions

Apache CloudStack version: main branch (4.23.0.0-SNAPSHOT)
Environment: GitHub Actions Simulator CI (advanced zone), simulator hypervisor — not a real deployment

### The steps to reproduce the bug

1. Run the Simulator CI test suite including component/test_mm_domain_limits.py
2. Observe test_03_delete_vm
3. deployVirtualMachine fails with errorCode 535 (memory limit exceeded)
4. Test then attempts to delete a VM that was never created, causing a failure

Can also be reproduced locally with:
nosetests-3.4 --with-marvin --marvin-config=setup/dev/advdualzone.cfg test/integration/component/test_mm_domain_limits.py:test_03_delete_vm -s -a tags=advanced

### What to do about it?

Update test_03_delete_vm in test/integration/component/test_mm_domain_limits.py to treat the CloudStack API errorCode 535 (memory resource limit exceeded) as an expected outcome, and only attempt VM deletion if creation succeeded. Example:

try:
vm = VirtualMachine.create(self.apiclient, ...)
vm_created = True
except CloudstackAPIException as ex:
if "errorCode: 535" in str(ex) or "Maximum amount of resources of Type = 'memory'" in str(ex):
vm_created = False
else:
raise

if vm_created:
vm.delete(self.apiclient)

Alternatively, the domain/project memory limit could be raised in test setup if VM creation is expected to succeed in this test.

Comece com test/integration/component/test_mm_domain_limits.py e inspecione test_03_delete_vm; em seguida, execute o comando nosetests focado com a configuração avançada do simulador. Verifique se errorCode 535 é tratado como um resultado esperado, se erros inesperados da API ainda causam falha e se a exclusão é tentada somente quando a criação da VM é bem-sucedida.
