Improvement Request : Adjust security groups more flexibly

##### ISSUE TYPE
* Improvement Request

##### COMPONENT NAME
~~~
Security Group
~~~

##### CLOUDSTACK VERSION
~~~
4.19.1.2
~~~

##### CONFIGURATION
~~~
Basic or Advanced networking with Security Group
~~~

##### OS / ENVIRONMENT

##### SUMMARY
~~~
We should be able to add, change or delete security group rules while the instance is running.
Sometimes we need to change the security group for some testing or security protection purposes. However, currently, we are unable to switch to another security group rules while the instance is running. As a result, we have no choice but to affect more instance or stop the instance , change the security group, and then start the instance again.

##### STEPS TO REPRODUCE

##### EXPECTED RESULTS

~~~
We should be able to add, change or delete security group rules while the instance is running.

Comienza con el componente Security Group y revisa cómo Basic y Advanced networking aplican grupos de seguridad a las instancias en ejecución. Define el comportamiento para añadir, cambiar y eliminar reglas sin detener ni reiniciar una instancia. Se considera terminado cuando estas operaciones funcionan mientras la instancia permanece en ejecución en las configuraciones compatibles.
