[yang] sonic-mirror-session.yang does not align with ConfigDb

[ganglyu]

Description

sonic-mirror-session.yang uses leaf-list for for src_port:
https://github.com/sonic-net/sonic-buildimage/blob/master/src/sonic-yang-models/yang-models/sonic-mirror-session.yang#L157

But src_port is not a list in ConfigDB:
admin@vlab-01:~$ sudo config mirror_session erspan add mrr_port 1.2.3.4 20.21.22.23 8 100 1234 0 Ethernet0

admin@vlab-01:~$ redis-cli -n 4 hgetall "MIRROR_SESSION|mrr_port"

1. "type"
2. "ERSPAN"
3. "src_ip"
4. "1.2.3.4"
5. "dst_ip"
6. "20.21.22.23"
7. "dscp"
8. "8"
9. "ttl"
10. "100"
11. "gre_type"
12. "1234"
13. "queue"
14. "0"
15. "src_port"
16. "Ethernet0"
17. "direction"
18. "BOTH"

1. Config MIRROR_SESSION table
2. Dump ConfigDB

@praveen-li @Junchao-Mellanox Could you help investigate this issue? It is similar to port lanes attribute.

[Junchao-Mellanox]

I suppose this is by design. Redis hash type does not support list value. So, any field defined as leaf-list will be translated into a comma separated string. @praveen-li , correct me if I am wrong.
