If the Infrastructure.Status.ControlPlaneTopology is set to 'External', the console-operator will pass this information via the console-config.yaml co the console. Console pod will get re-deployed and will store the topology mode information as a SERVER_FLAG. Based on that value we need to show or hide Machine related resources in the console. Those resources are:

• Remove MachineConfigs
• Remove MachineConfigPools 
• Remove Machines
• Remove MachineSets
• Remove MachineAutoscalers
• Remove MachineHealthChecks

AC:

• Remove Machine related resources from nav section
• Remove Machine related resources from CRD list
• Remove Machine related resources from search page
• Remove Machine related resources from search filter
