**- 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

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

This PR adds the ability to read environment file from /etc/sonic.
the file contains immutable SONiC config attributes such as platform,
hwsku, version, device_type. The aim is to minimize calls being made
into sonic-cfggen during boot time.

When stopping the swss, pmon or bgp containers, log messages like the following can be seen:
```
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,061 ERRO pool dependent-startup event buffer overflowed, discarding event 34

```
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.

Printing both snapshot and current counter sets will make it easier to pinpoint
which message type(s) is/are not being relayed. This PR prints both counter sets.
Also, this PR defines gnu11 as a C standard to compile with in order to avoid

When BGP routes are missing, DHCP packets get relayed over mgmt
interface. This results in dhcpmon alerting that DHCP packets are
not being relayed. This is PR include mgmt interface as uplink
device, and so, if DHCP packet gets relayed over mgmt interface,
regular dhcpmon alert will not be issues. Instead, dhcpmon will
check the mgmt interface counts and issue a separate alert regarding
packets travelling through mgmt network.
In addition, this PR includes the following enhancements:
1. Add SIGUSR1 handler that prints out current packet counts
2. Increase alert grace window to 3 minutes from currently 2 minutes
3. Time is now computed more accurately
4. Print vlan name before counters

**- Why I did it**
PR https://github.com/Azure/sonic-buildimage/pull/4599 introduced two bugs in the startup of the router advertiser container:
1. References to the `wait_for_intf.sh` script were changed to `wait_for_link.sh`, but the actual script was not renamed
2. The `ipv6_found` Jinja2 variable added to the supervisor config file goes out of scope before it is read.
**- How I did it**
1. Rename the `wait_for_intf.sh` script to `wait_for_link.sh`
2. Use the Jinja2 "namespace" construct to fix the scope issue
**- How to verify it**
Ensure all processes in the radv container start properly under the correct conditions (i.e., whether or not there is at least one VLAN with an IPv6 address assigned).

Root Cause: Waiting on Restore count != 0 can lead to race condition
between orchagent process and swssconfig.sh.
Ideally check of Restore count != 0 is not needed as the State DB
cannot be flushed as if it was flushed then Warm Restart or swss-restart
should not be true also.

The following changes are done.
- Multi asic platform have 2 Loopback interfaces, Loopback0 and Loopback4096. IPinIP decap entries need to be added for both of them. Update the ipinip.json.j2 template to add decap entries for Loopback4096.
- Add corressponding unit test
For telemetry regression test we need gnmi client to be present on ptfdocker. Gnmi-server will be present on SONiC DuT. Further, we can access gnmi_get from ptfdocker inside pytest to verify gnmi server streaming data successfully or not.
When telemetry is in secure mode ,the monitor will have error log of the match string "--insecure". So I modify to be compatiable with insecure mode and secure mode.

The template is referenced relative to the script path and this could
results in errors in case script is run from root. Add explicit
path to the template file name.

when portsyncd starts, it first enumerates all front panel ports
and marks them as old interfaces. Then, for new front panel ports
it checks if their indexes exist in previous sets. If yes, it will
treats them as old interfaces and ignore them.
The reason we have this check is because broadcom SAI only removes
front panel ports after sai switch init.
So, if portsyncd starts after orchagent, new interfaces could be
created before portsyncd and treated as old interface.
