Update DNS servers on central region and check it is propagated to subclouds
Args:
snmp_precheck: test fixture for setup/teardown
Setups:
- Ensure primary subcloud is managed and SNMP config is synced
Test Steps:
- Un-manage primary subcloud
- Add a SNMP community string and a trapdest on unmanaged subcloud locally
- Add a different SNMP community string and trapdest on central region
- Wait for new SNMP configs to sync over to managed online subclouds
- Ensure central SNMP configs are not updated on unmanaged primary subcloud
- Re-manage primary subcloud and ensure DNS config syncs over
- Verify nslookup works in Central Region and primary subcloud
Teardown:
- Delete DNS servers to original value (module)
