Reduce load on the APIServer

[prashanth26]

Issue

• MCM creates significantly more requests on the endpoints resource than MCM resources. This is from the leader election module.
• This has been handled as MCM uses leases for leader election now. Migrate leader election to leases #711 Switch leader election to endpointleases #662 Leader election defaults were updated #203
• Reduce frequent updates to machine objects
• Relook at design decision of duplicating node conditions in machine status , as that lead to a lot of machine obj updates.

Solution

Need to minimize them
