Correctly wait for upto MachineCreationTimeout in waitForServerStatus

[elankath]

In Executor.CreateMachine invoked by Driver.CreateMachine we have HARD-CODED the provisioning time for the openstack Server object when waiting for it to become active to 1200 seconds. See

machine-controller-manager-provider-openstack/pkg/driver/executor/executor.go

Line 137 in 07427c6

activeServer, err = ex.waitForServerStatus(ctx,

var activeServer *servers.Server  
activeServer, err = ex.waitForServerStatus(ctx,  
    server.ID,  
    []string{client.ServerStatusBuild},  
    []string{client.ServerStatusActive}, 1200)  
if err != nil {  
    return nil, deleteOnFail(fmt.Errorf("error waiting for server [ID=%q] to reach target status: %w", server.ID, err))  
}

This is incorrect. We should use machine.Spec.MachineConfiguration.MachineCreationTimeout. In future effective MachineCreationTimeout's will be adjusted by the gardener/dependency-watchdog and should be honored by MCM and providers.
