What this PR does / why we need it:
doc: deprecate AzureStorageIdentityObjectID field

from blobfuse 2.3.0, AzureStorageIdentityObjectID relies on azure cli installed on the node, pls use
AzureStorageIdentityClientID or
AzureStorageIdentityResourceID parameter instead.

CX needed to install Azure CLI on worker nodes manually.

With this PR, ObjectID (Managed Identity Authentication) now relies on the azure cli.

volumeAttributes:.
  AzureStorageAuthType: msi
  AzureStorageIdentityObjectID: XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

Every time CX reimages a worker node with nodeOSimage Upgrade, the Azure CLI needs to be installed manually.

To avoid having to install Azure CLI on worker nodes, user should use AzureStorageIdentityClientID or AzureStorageIdentityResourceID instead of AzureStorageIdentityObjectID
