It's not necessary to have the dcagent keystone user present on
system controller. Its presence can cause problems during upgrade
as it would be necessary for the dcagent user in the subcloud to
have the same password as system controller upon creation (before
dcdbsync synching upon managing the subcloud).
Test plan:
- PASS: Build a developer ISO. Deploy a DC system with 2 system
controllers and 1 subcloud. Verify the dcagent user is
created only on the subcloud.
- PASS: Manage the subcloud and verify the dcagent service is
working as expected.
- PASS: Perform a network reconfiguration on the subcloud. Verify
the operation finishes successfully.
