This commit solves the delay in factory install
playbook tasks that was caused by hostname resolution,
removing the variable from meta-data file will ensure
the system uses localhost until controller-0 host
entries and hostname are configured.
Test Plan:
PASS: Follow the standard Factory Install procedure and
verify that the factory install process executes without
delay in the playbook tasks.
PASS: Factory install and enroll a subcloud. Verify that
the subcloud enrollment completes successfully.
