vrf: T3344: move dynamic routing protocols under "vrf name <name> protocols"
Instead of having the dynamic routing protocols OSPF and BGP residing under the "protocols vrf <name> [ospf|bgp]" nodes, rather move them directly under the "vrf name <name> protocols [ospf|bgp]" node. Now all VRF related parts are placed under the same root node. This eases the verify steps tremendously, as we do not need to check wheter a VRF eists or not, it will always exist as we operate under a child node.
