AGENT-860: Update configure command to handle multiple HostConfigs

[rwsu]

for day-2/addnodes workflow.

Updated the LoadHostConfigs function to only load the current host's HostConfig if the workflow is addnodes.

Only the current host's HostConfig is needed because each host in the addnodes workflow has its own assisted-service. Loading other node's HostConfigs would cause the apply-host-config service to continually wait for other hosts to register with assisted-service because each node is added in isolation.
