Device features advertised in capability for imported model should be considered

[ghost]

If a device advertises feature compliance in a model 'x' that is imported by model 'y', these features must be considered by YDK when validating the yang models.

Current behavior

Currently, because the features from hello message capabilities are not correctly parsed, something like the below error occurs

ydk.errors.YCoreError:  YCodecError:Unknown element "ipsec".. Path: /Cisco-IOS-XE-native:native/interface/Tunnel[name='1']/Cisco-IOS-XE-tunnel:tunnel/protection/Cisco-IOS-XE-crypto:ipsec

or

YError: YCodecError:Unknown element "bundle-name".. Path: /Cisco-IOS-XE-native:native/multilink/Cisco-IOS-XE-ppp:bundle-name

from ydk.models.cisco_ios_xe import Cisco_IOS_XE_native 

native=Cisco_IOS_XE_native.Native()
tunnel = native.interface.Tunnel()
tunnel.name = 1
tunnel.tunnel.destination = '172.58.2.1'
tunnel.ip.address.primary.address = '192.168.1.1'
tunnel.ip.address.primary.mask = '255.255.255.252'
tunnel.tunnel.source = 'GigabitEthernet0/0/0'
tunnel.tunnel.protection.ipsec.profile = 'ipsec-profile'
tunnel.tunnel.protection.ipsec.ikev2_profile = 'ikev2-profile'
native.interface.tunnel.append(tunnel)

I could not reproduce the issue when using lab device XE16.7.1 and path API:

        # Create a NetconfSession instance to connect to the device
        netconf_session = NetconfSession('10.30.110.87', 'admin', 'admin')
        root = netconf_session.get_root_schema()

        native = root.create_datanode("Cisco-IOS-XE-native:native")

        tunnelInt = native.create_datanode("interface/Tunnel[name='521']")

        # Configure tunnel
        tunnel = tunnelInt.create_datanode("Cisco-IOS-XE-tunnel:tunnel")
        tunnel.create_datanode("source", "GigabitEthernet0/0/0")
        tunnel.create_datanode("destination", "172.58.2.1");

        # Tunnel Interface IP address
        ip = tunnelInt.create_datanode("ip")
        address = ip.create_datanode("address/primary")
        address.create_datanode("address", "192.168.1.1")
        address.create_datanode("mask", "255.255.255.252")

        # Protection IPsec
        ipsec = tunnel.create_datanode("protection/Cisco-IOS-XE-crypto:ipsec")
        ipsec.create_datanode("profile","ipsec-profile")
        ipsec.create_datanode("ikev2-profile","ipsec-ikev2-profile")

        c = Codec()

        xml = c.encode(native, EncodingFormat.XML, True)
        print(xml)

See attached log for details:

Looks like you are using codec.encode(). Can you try to write to the device using Rpc?

Resolved the bug. Added core test case, which uses MockSession class.
