Add -Feature and -AllowUpdateImage parameters to Update-AzGalleryImageDefinition

[Copilot]

Update-AzGalleryImageDefinition lacked the ability to update existing gallery image features (e.g. DiskControllerTypes, SecurityType, IsAcceleratedNetwork, IsHibernate) or signal that a feature update is intentional. The SDK models already supported both Features (with StartsAtVersion) and AllowUpdateImage, but the cmdlet didn't expose them.

Changes

• Cmdlet (GalleryImageCreateOrUpdateMethod.cs): Added -Feature (GalleryImageFeature[]) and -AllowUpdateImage (bool) parameters to UpdateAzureRmGalleryImage, with IsParameterBound-guarded execution logic.
• PS model (PSGalleryImage.cs): Added AllowUpdateImage (bool?) property so AutoMapper correctly round-trips the field from the API response.
• Help (Update-AzGalleryImageDefinition.md): Updated all three parameter-set SYNTAX blocks, added parameter docs, and added an example for the new feature-update flow.
• Tests: Added Test-GalleryImageDefinitionUpdateFeature (PS) and TestGalleryImageDefinitionUpdateFeature (C#) covering feature creation with StartsAtVersion and verification of AllowUpdateImage on the updated definition.
• Changelog: Documented both new parameters under ## Upcoming Release.

Example

$diskFeature = @{Name='DiskControllerTypes'; Value='SCSI'; StartsAtVersion='4.0.0'}
$secFeature  = @{Name='SecurityType';        Value='TrustedLaunch'; StartsAtVersion='4.0.0'}

Update-AzGalleryImageDefinition `
    -ResourceGroupName $rgname `
    -GalleryName       $galleryName `
    -Name              $imageDefinitionName `
    -Feature           @($diskFeature, $secFeature) `
    -AllowUpdateImage  $true

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
