sonic-mgmt-common: Support for L2 match fields for L2 ACL table

[ArthiGovindaraj]

• Added SONIC yang for src mac, dst mac, vlan id, vlan pcp, vlan dei
• This is updated for schema reference purpose.
  Added support for L2_TABLE related match fields for configuring rules to ACL L2 TABLE

sonic-net/sonic-swss#2554
[https://github.com/sonic-net/sonic-utilities/pull/2516

Why I did it

ACL supports only L3 and L3V6 table type. There is no support for matching L2 fields.
When user wants to match fields like SRC_MAC, DST_MAC, VLAN_ID, VLAN_PCP, VLAN_DEI we do not have support for these fields in sonic yang.
Added support for these fields in sonic-acl.yang.

How I verified it

Create L2 Table from CLICK
"config acl add table -s ingress -p <table_name> L2"
Add rules using CONFIG_DB format
add rules src mac, dst mac, ether type, pcp, dei & vlan id
"L2_TABLE|RULE_2": {
"SRC_MAC": "00:00:00:11:11:11/00:00:00:ff:ff:ff",
"DST_MAC": "00:00:00:22:22:22/00:00:00:ff:ff:ff",
"ETHER_TYPE": "0x0800",
"VLAN_ID": "100",
"VLAN_PCP": "5/7",
"VLAN_DEI": "1",
"PRIORITY": "5",
"PACKET_ACTION": "DROP"
}
Validate commands "show acl table"
Validate commands and fields in "show acl rule"
Validate commands "aclshow -a" /* Ensured that the counters are hitting the relevant rule */
Add rules using openconfig json format for supported fields "config acl update full/incremental <file.json>"
"source-mac": "00:00:00:11:11:12",
"source-mac-mask": "00:00:00:ff:ff:ff",
"destination-mac": "00:00:00:11:11:13",
"destination-mac-mask": "00:00:00:ff:ff:ff",
"ethertype": "ETHERTYPE_ARP"
All the rules are added for each field and combinations as well. and each field tested with traffic in Broadcom based platform.

Please inform are these changes merged to master branch ? Does master code base have support for L2 ACL for MAC address ?
