As a developer I want to add the webhook validation for the "CapacityReservationGroupID" field of "AzureMachineProviderSpec" in openshift/machine-api-operator so that Azure capacity reservation can be supported.

Background

CFE-1036 adds the support of Capacity Reservation in upstream CAPZ (PR). The same support is needed to be added downstream also. Please refer the upstream PR for adding support downstream.

Slack discussion regarding the same: https://redhat-internal.slack.com/archives/CBZHF4DHC/p1713249202780119?thread_ts=1712582367.529309&cid=CBZHF4DHC_

Steps

• Add the validation for "CapacityReservationGroupID" to "AzureMachineProviderSpec"
• Add tests to validate.

Stakeholders

• Cluster Infra
• CFE
