Yang model for xcvr tx power and frequency configuration

[prgeor]

Why I did it

Add yang model for configuring TX power and laser frequency of ZR transceiver module

How to verify it

root@sonic:~#  config interface transceiver tx_power Ethernet0 -- -27.3
Setting target Tx output power to -27.3 dBm on port Ethernet0
root@sonic:~# redis-cli -n 4 hgetall "PORT|Ethernet0"                  
 1) "admin_status"
 2) "up"
 3) "alias"
 4) "Ethernet1/1"
 5) "index"
 6) "1"
 7) "lanes"
 8) "1,2,3,4,5,6,7,8"
 9) "laser_freq"
10) "170000"
11) "speed"
12) "400000"
13) "tx_power"
14) "-27.3"
root@sonic:~# 

root@sonic:~# config interface transceiver tx_power Ethernet0 -27   
Usage: config interface transceiver tx_power [OPTIONS] <interface_name> <tx-
                                             power>
Try "config interface transceiver tx_power -h" for help.

Error: no such option: -2

root@sonic:~# config interface transceiver frequency Ethernet0 -1
Usage: config interface transceiver frequency [OPTIONS] <interface_name>
                                              <frequency>
Try "config interface transceiver frequency -h" for help.

Error: no such option: -1

root@sonic:~# config interface transceiver frequency Ethernet0 1000
Setting laser frequency to 1000 GHz on port Ethernet0
root@sonic:~# redis-cli -n 4 hgetall "PORT|Ethernet0"
