With python 2.7, import yaml module was resulting in huge memory allocation in the heap per process. As an interim fix, moving the import yaml to the function which actually uses this module. This helps reduce the memory footprint of pmon docker, as it don't use the API's which need yaml processing.
This issue not seen with importing yaml with python3, Need to be further analyzed, hence putting this fix in 201911 where we continue to use python2.7.

**- Why I did it**
FRR introduced [next hop tracking](http://docs.frrouting.org/projects/dev-guide/en/latest/next-hop-tracking.html) functionality.
That functionality requires resolving BGP neighbors before setting BGP connection (or explicit ebgp-multihop command). Sometimes (BGP MONITORS) our neighbors are not directly connected and sessions are IBGP. In this case current configuration prevents FRR to establish BGP connections. Reason would be "waiting for NHT". To fix that we need either add static routes for each not-directly connected ibgp neighbor, or enable command `ip nht resolve-via-default`
**- How I did it**
Put `ip nht resolve-via-default` into the config
**- How to verify it**
Build an image. Enable BGP_MONITOR entry and check that entry is Established or Connecting in FRR

- Platform API implementation using sonic-cfggen to get platform name and SKU name, which will fail when the database is not available.
- Chassis name is not correctly assigned, it shall be assigned with EEPROM TLV "Product Name", instead of SKU name
- Chassis model is not implemented, it shall be assigned with EEPROM TLV "Part Number"
**- How I did it**
1. Chassis
> - Get platform name from /host/machine.conf
> - Remove get SKU name with sonic-cfggen
> - Get Chassis name and model from EEPROM TLV "Product Name" and "Part Number"
> - Add function to return model
2. EEPROM
> - Add function to return product name and part number
3. Platform
> - Init EEPROM on the host side, so also can get the Chassis name model from EEPROM on the host side.

BGP_MONITORS sessions don't have corresponding DEVICE_NEIGHBOR_METADATA CONFIG_DB entries in the minigraphs. Prevent bgpcfgd to wait on such entries for BGP_MONITORS sessions.
**- How I did it**
Set constructor argument to False that means - don't wait for device neighbors metadata info for BGP_MONITORS
**- How to verify it**
Build an image, write on your device, use a minigraph with BGP_MONITORS sessions. Check that sessions are populated in the config.

This feature allows us to control which IP prefixes are going to be advertised via ebgp from the routes received from EBGP neighbors.

Refactor SFP reset, low power get/set API, and plugins with new SDK SX APIs. Previously they were calling SDK SXD APIs which have glibc dependency because of shared memory usage.
Remove implementation "set_power_override", "tx_disable_channel", "tx_disable" which using SXD APIs, once related SDK SX API available, will add them back based on new SDK SX APIs.

* No need to clean up the exising NAT rules if present, which could be created by some other process.
* Delete our rule first and add it back, to take care of caclmgrd restart.
Another benefit is that we delete only our rules, rather than earlier approach of "iptables -F" which cleans up all rules.
* Keeping the original logic to clean the NAT entries, to revist when NAT feature added in namespace.
* Missing updates to log_info call.
When stopping the swss, pmon or bgp containers, log messages like the following can be seen:
```

```
This is due to the number of programs in the container managed by supervisor, all generating events at the same time. The default event queue buffer size in supervisor is 10. This patch increases that value in all containers in order to eliminate these errors. As more programs are added to the containers, we may need to further adjust these values. I increased all buffer sizes to 25 except for containers with more programs or templated supervisor.conf files which allow for a variable number of programs. In these cases I increased the buffer size to 50. One final exception is the swss container, where the buffer fills up to ~50, so I increased this buffer to 100.
