ProfileX is defined at the folder level but modified at the device level (override a
named profile) or (inherit profile but edit variables) as follows:
Information is inherited from ProfileX.
HOSTNAME=Test-Hostname
GATEWAY=172.17.1.1
Make some changes.
HOSTNAME=TestDevice
GATEWAY is cleared to null
After the modification, the variables that are not null (empty string) are saved and
applied at the device level. In this case, the CLI Profile (ProfileX) is merged with
the CLIVars which yields the following results:
HOSTNAME=TestDevice
GATEWAY=172.17.1.1
The result of this combination will result in the HOSTNAME coming from the CLIVars
and the GATEWAY coming from the CLI Profile (ProfileX)
