[Orchagent] Vxlanorch and Portsorch changes for EVPN VXLAN (sonic-net…

…#1264) * https://github.com/Azure/SONiC/pull/437/commits 1. Existing code supports a single mapper type to be created. Either BRIDGE or VRF type mappers are supported. Change to support multiple mapper type creations is being added. 2. Changes to support P2P tunnel creation and deletion. A refcnt is maintained per resource type (IMR or IP prefix) and based on this a P2P tunnel is created or deleted. 3. Changes to support handling of VXLAN_REMOTE_VNI table. Interfaces with portsorch to create a Port object of type TUNNEL on tunnel discovery. 4. SAI interface function changes to support P2P tunnels. 5. EVPN NVO table handling.
