Jovatn/ospf deviations

[jovatn]

Description

Adding deviation statements in infix-routing.yang for non-supported OSPF RPCs and Notifications declared in ietf-ospf.yang.

Other information

Before the fix, pyang would list OSPF RPCs and Notifications.

                +--ro v6ur:destination-prefix?   inet:ipv6-prefix

module: ietf-ospf

  rpcs:
   +---x clear-neighbor
   |  +---w input
   |     +---w routing-protocol-name    -> /rt:routing/control-plane-protocols/control-plane-protocol/name

   +---x clear-database

         +---w routing-protocol-name    -> /rt:routing/control-plane-protocols/control-plane-protocol/name

  notifications:
   +---n if-state-change
   |  +--ro routing-protocol-name?   -> /rt:routing/control-plane-protocols/control-plane-protocol/name

Before fix, sysrepocfg can probe for RFC, be it with a failure message

admin@infix:~$ cat file.json
{
   "ietf-ospf:clear-neighbor": {
  "routing-protocol-name": "default"
   }
}
admin@infix:~$ sysrepocfg -fjson -R file.json
[ERR] There are no matching subscribers for RPC/action "/ietf-ospf:clear-neighbor".
sysrepocfg error: Sending RPC/action failed (Operation not supported)
For more details you may try to increase the verbosity up to "-v3".
admin@infix-7e-ff-ff:~$

After fix, sysrepocfg does not recognize the RPC

admin@infix:~$ sysrepocfg -fjson -R file.json 
libyang[0]: Node "clear-neighbor" not found in the "ietf-ospf" module. (line: 2)
libyang error: Node "clear-neighbor" not found in the "ietf-ospf" module.
sysrepocfg error: Data parsing failed
