Why I did it
portconfig.py gets PORT table from config_db if it is present. If not, port_config.ini files are parsed.
For multi-asic platform, if namespace is passed to get_port_config(), config_db connection was done to host namespace always and not to asic specific namespace.
Provides fix for: #7161
How I did it
Modify db connection function to connect to namespace config_db.
To fix [DPB| wrong aliases for interfaces](https://github.com/Azure/sonic-buildimage/issues/6024) issue, implimented flexible alias support [design doc](https://github.com/Azure/SONiC/pull/749)
> [[dpb|config] Fix the validation logic of breakout mode](https://github.com/Azure/sonic-utilities/pull/1440) depends on this
#### How I did it
1. Removed `"alias_at_lanes"` from port-configuration file(i.e. platfrom.json)
2. Added dictionary to "breakout_modes" values. This defines the breakout modes available on the platform for this parent port, and it maps to the alias list. The alias list presents the alias names for individual ports in order under this breakout mode.
```
{
"interfaces": {
"Ethernet0": {
"index": "1,1,1,1",
"lanes": "0,1,2,3",
"breakout_modes": {
"1x100G[40G]": ["Eth1"],
"2x50G": ["Eth1/1", "Eth1/2"],
"4x25G[10G]": ["Eth1/1", "Eth1/2", "Eth1/3", "Eth1/4"],
"2x25G(2)+1x50G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"],
"1x50G(2)+2x25G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"]
}
}
}
```
#### How to verify it
`config interface breakout`

**- Why I did it**
For now `hwsku.json` and `platform.json` dont support optional fields. For example no way to add `fec` or `autoneg` field using `platform.json` and `hwsku.json`.
**- How I did it**
Added parsing of optional fields from hwsku.json.
**- How to verify it**
Add optional field to `hwsku.json`. After first boot will be generated new `config_db.json` or you can generate it using `sonic-cfggen` command. In this file must be optional field from `hwsku.json` or check using command `redis-cli hgetall PORT_TABLE:Ethernet0`
Example of `hwsku.json`, that must be parsed:
```
{
"interfaces": {
"Ethernet0": {
"default_brkout_mode": "1x100G[40G]",
"fec": "rs",
"autoneg": "0"
},
...
}
```
Example of generated `config_db.json`:
```
"PORT": {
"Ethernet0": {
"alias": "Ethernet0",
"lanes": "0,1,2,3",
"speed": "100000",
"index": "1",
"admin_status": "up",
"fec": "rs",
"autoneg": "0",
"mtu": "9100"
},
```
So, we can see this entries in redis db:
```
admin@sonic:~$ redis-cli hgetall PORT_TABLE:Ethernet0
1) "alias"
2) "Ethernet0"
3) "lanes"
4) "0,1,2,3"
5) "speed"
6) "100000"
7) "index"
8) "1"
9) "admin_status"
10) "up"
11) "fec"
12) "rs"
13) "autoneg"
14) "0"
15) "mtu"
16) "9100"
17) "description"
18) ""
19) "oper_status"
20) "up"
```
Also its way to fix `show interface status`, `FEC` field but also need add `FEC` field to `hwsku.json`.
Before:
```
admin@sonic:~$ show interfaces status
Interface Lanes Speed MTU FEC Alias Vlan Oper Admin Type Asym PFC
----------- --------------- ------- ----- ----- ----------- ------ ------ ------- --------------- ----------
Ethernet0 0,1,2,3 100G 9100 N/A Ethernet0 routed up up QSFP28 or later N/A
```
After:
```
admin@sonic:~$ show interfaces status
Interface Lanes Speed MTU FEC Alias Vlan Oper Admin Type Asym PFC
----------- --------------- ------- ----- ----- ----------- ------ ------ ------- --------------- ----------
Ethernet0 0,1,2,3 100G 9100 rs Ethernet0 routed up up QSFP28 or later N/A
```

* [sonic-utilities]update submodule with fix
This PR addresses fixes in sonic-py-common to imitate the behavior inside
sonic-cfggen. Essentially this is a fix for accessing the port-config file.
First check if there is a platform.json file for config generation
and then for legacy port_config.ini.
Also updating the sub-module sonic-utilities.

**- What I did**
Add support of **platform.json** parsing to **portconfig.py** file which is being used by **_sonic-cfggen_** and ***minigraph.py*** file under ***src/sonic-config-engine*** folder to get port config via get_port_config function.
**- How I did it**
1. **portconfig.py** file will first check whether the **platform.json** file is there or not. if not then whether port_config.ini file is there or not. Modified **get_port_config_file_name** for this purpose.
2. Added two separate functions i.e. **parse_platform_json_file** to get port attributes from **platform.json** and **gen_port_config** to generate port attributes.
3. Added another two functions i.e get_breakout_mode parse_breakout_mode to get breakout mode and parse breakout mode from platform.json respectively.
**- How to verify it**
rebuilt "sonic_config_engine-1.0" wheel package with all the test cases.All the below-mentioned test cases passed.
```
# Check whether all interfaces present or not as per platform.json
def test_platform_json_interfaces_keys(self):
# Check specific Interface with it's proper configuration as per platform.json
def test_platform_json_specific_ethernet_interfaces(self):
# Check all Interface with it's proper configuration as per platform.json
def test_platform_json_all_ethernet_interfaces(self):

Move port_config.ini related parsing code out of minigraph.py and create an independent portconfig.py.
Add support to multiple optional fields according to Porting Guide
