Let's drop the leading IETF or Infix prefixes from tests. Initially the idea was to mimnic the YANG models, but it's difficult to navigate and does not provide any real benefit to developers or end-users. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

"""DHCP Hostname Priority

Verify deterministic hostname management: a DHCP acquired hostname takes

precedence over a configured hostname. When a DHCP lease ends, or the

hostname option is removed, the system should revert to the configured

hostname.
