GetOptions implementation of NodeGroup interface does not return the default values for some options

[rishabh-11]

What happened:
GetOptions implementation of NodeGroup interface does not return the default values for some options. The reason for this is in the code

autoscaler/cluster-autoscaler/cloudprovider/mcm/mcm_cloud_provider.go

Line 480 in 1772ba0

func (machinedeployment *MachineDeployment) GetOptions(defaults config.NodeGroupAutoscalingOptions) (*config.NodeGroupAutoscalingOptions, error) {

, we do not set the default values for these options even though they are configured via the CA flags.

What you expected to happen:
GetOptions should return the correct values for all the options (along with proper defaults).
