sr: support define src ipv6 per encap policy
Can to define src ip of outer IPv6 Hdr for each encap policy. Along with that, I decided to develop it as API version V2. This is useful in the SRv6 MUP case. For example, it will be possible to handle multiple UPF destinations. Type: feature Change-Id: I44ff7b54e8868619069621ab53e194e2c7a17435 Signed-off-by: Takeru Hayasaka <hayatake396@gmail.com>
