K8SPSMDB-1472 introduce grouping of storageScaling options

[gkech]

Due to the high volume of requests, we're unable to provide free service for this account. To continue using the service, please upgarde to a paid plan.

CHANGE DESCRIPTION

Problem:

Given that a lot storage scaling related options started to appear on the top level of the spec file, we can combine them together under the following:

# storageScaling:
#   enableExternalAutoscaling: false
#   enableVolumeScaling: false
#   autoscaling:
#     enabled: false
#     triggerThresholdPercent: 80
#     growthStep: 2Gi
#     maxSize: "10Gi"

We are also introducing a validation rule on CRD level that autoscaling cannot be enabled when enableVolumeScaling is disabled.

Cause:
Short explanation of the root cause of the issue if applicable.

Solution:
Short explanation of the solution we are providing with this PR.

@gkech please update helm chart PR

[egegunes]

any reason to duplicate this?

[egegunes]

should we also validate for EnableExternalAutoscaling ?

[gkech]

Can you elaborate what we should validate here? Related to autoscaling or the EnableVolumeScaling?
