zebra: Add CLI command to verify SRv6 Manager

Browse source 
Add a new CLI command `show segment-routing srv6 manager [json]` to
verify the overall SRv6 state. The current output displays only the
configured source address of outer encapsulating IPv6 header. The output
can be extended in the future to show more information, including
summary SRv6 information and supported capabilities.

Example:

```
r1# show segment-routing srv6 manager
Parameters:
  Encapsulation:
    Source Address:
      Configured: fc00:0:1::1

r1# show segment-routing srv6 manager json
{
  "parameters":{
    "encapsulation":{
      "sourceAddress":{
        "configured":"fc00:0:1::1"
      }
    }
  }
}
```
