User Story:

As a developer working on the agent-based installer, I want to be able to:

• Save hostnames into a new file (hostnames) that can be read by the ABI client in the Assisted Service. Currently, ABI saves mac addresses in a file mac_addresses Ref HostConfigFiles() from installer/pkg/asset/agent/agentconfig/agenthosts.go

so that I can achieve

• Use hostnames to define roles for hosts when MAC addresses are not available.
• Ensure the ABI client can retrieve hostname-based role assignments efficiently.
• Reduce dependency on network-related configurations for setting host roles.
