Set the Status of some topology nodes

[caiocmpaes]

What this PR does:

• Set the status of the PhysicalChassis and PhysicalStorage nodes in the topology view to be relative to the entity's health_state;
• Set the status of the Hosts nodes in the topology view to be relative to the entity's state;
• Set the status of the Vms nodes in the topology view to be relative to the entity's power_state.

Note: Physical Chassis and Physical Storage were added because as soon as they are added to the topology, the status border will work for them.

As the picture shows, the nodes get borders in one of this colors:

• Gray => Unknown Health State status (Chassis/Storage) or Power State status (Host/VM);
• Green => Valid or On;
• Yellow => Warning;
• Red => Critical;

@skateman this pull request adds status in nodes to the physical infra topology view.

With this new four nodes, the topology will be completed. This is a continuation of #4288

Why just Redhat::InfraManager, what about all the others? Shouldn't be these simply just Host and Vm?

You're right. I fixed these unnecessary namespaces use. 😄
