AGENT-1179: Return console-url for agent-installer (#7510)

The console-url should be returned prior to cluster completion for
the agent-installer. This url is necessary for display in the OVE UI
prior to the operator being available since it can't be accessed
via this endpoint when the cluster installation is complete for the
agent-installer.
