CAFV-393: Do not update VAppMetadataUpdated anymore

[arunmk]

Description

Please provide a brief description of the changes proposed in this Pull Request

• This stops updating the vAppMetadataUpdated field. The VCDResourceSet already contains the list of vApps consumed by the cluster. This field is not needed anymore.
• This does not remove any race scenarios.
• This field can remove the number of VCD API calls while a cluster is being created by 1 call per reentry to the reconciler. That is a small tax when the number of calls is considered. This can be reduced by other means as well.

Checklist

• tested locally
