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 Server Basic
|
|
|
|
Verify basic DHCP server functionality. The server is set up to only
|
|
hand out leases from a pool of a single address. A single DHCP option,
|
|
hostname, is to be handed out with the lease to the client. Ensure no
|
|
other options are sent by checking, e.g., that the client has not set up
|
|
a default route to the server.
