Include updateMode to the updating replicas logic

[juliababkina]

Currently, in Skenario implemented the following updating replicas algorithm for vertical scaling:

• Iterate through replicas
• Check if we need to update this replica
  -Is the request < lowerBound or > UpperBound => update
  - If we need to update this replica
  - We evict this replica
  - We create new one according to the recommendation

We ignore updateMode state chosen for vpa object in UI. This parameter should be included to the updating replicas logic according to the existent one in VPA.
