ospf: T3267: move "interface ip ospf" configuration to "protocols ospf interface"

For easier maintenance and operability move the interface specific protocol
setting of OSPF to the OSPF protocol section. This is now also in-line with IS-IS.

This means to migrate:
 ethernet eth0 {
    vif 202 {
        ip {
            ospf {
                authentication {
                    md5 {
                        key-id 10 {
                            md5-key vyosvyos
                        }
                    }
                }
                dead-interval 40
                hello-interval 10
                priority 1
                retransmit-interval 5
                transmit-delay 1
            }
        }
    }
 }

to

 protocols {
    ospf {
        interface eth0.201 {
            authentication {
                md5 {
                    key-id 10 {
                        md5-key vyosvyos
                    }
                }
            }
            dead-interval 40
            hello-interval 10
            priority 1
            retransmit-interval 5
            transmit-delay 1
        }
 }
