The admin user in this case is the username specified as "admin"
when deploying VMs on Azure.
See https://docs.microsoft.com/en-us/cli/azure/vm#az-vm-create.
cloud-init expects a straightforward array of keys to be dropped
into the admin user's authorized_keys file. Azure control plane exposes
multiple public keys to the VM via wireserver. Select just the
admin user's key(s) and return them, ignoring any other certs.
@param goal_state: GoalState object. The GoalState object contains
a certificate XML, which contains both the VM user's authorized
pubkeys and other non-user pubkeys, which are used for
MSI and protected extension handling.
@param pubkey_info: List of VM user pubkey dicts that were previously
obtained from provisioning data.
Each pubkey dict in this list can either have the format
pubkey['value'] or pubkey['fingerprint'].
Each pubkey['fingerprint'] in the list is used to filter
and obtain the actual pubkey value from the GoalState
certificates XML.
Each pubkey['value'] requires no further processing and is
immediately added to the return list.
