Prepend "default " to unconfigure physical interfaces in Cisco IOS/NX-OS

[kornoa]

Method CiscoConfParse.sync_diff prepends "no " to unconfigure interfaces. This is correct for logical interfaces (sub-interfaces, loopbacks, tunnel, ...) but wrong for physical installed interfaces (Ethernet, Serial, ...).

Current behavior: loaded config:

[
    "interface Loopback0"
    "interface GigabitEthernet1/0",
    "interface Tunnel1001",
    "interface Serial2/0"
]

reference config: [] returns:

[
'no interface Loopback0',
'no interface GigabitEthernet1/0',
'no interface Tunnel1001',
'no interface Serial2/0'
]

Suggested behavior: Returns:

[
'no interface Loopback0',
'default interface GigabitEthernet1/0',
'no interface Tunnel1001',
'default interface Serial2/0'
]

If you accept the feature request, I can provide changes to classes IOSCfgLine and NXOSCfgLine and create a pull request.
