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

Dynamic threshold setting changed to 0 and WRED profile green min threshold set to 250000 for Tomahawk devices
Changed the dynamic threshold settings in pg_profile_lookup.ini
Added a macro for WRED profiles in qos.json.j2 for Tomahawk devices
Necessary changes made in qos.config.j2 to use the macro if present

* [bgpcfgd]: Generate set src configuration dynamically
Sometimes zebra starts faster then swss configures Loopback0
In this case "set src" inside of the route map will not be
inserted to the configuration because zebra doesn't see Loopback
ips in the list of available ip addresses.
I've added extra logic to push the "set src" configuration only
when Loopback has been configured by swss.
If sonic-cfggen is passed the -m argument (to load the minigraph file) along with one or more -j <json_file> arguments, load the JSON files before loading the minigraph file.
This ensures that the init_cfg.json file is loaded before the minigraph, therefore the minigraph can override any default configuration options specified in init_cfg.json. Currently, the behavior is reversed.
Note: This is not an issue if loading loading multiple JSON files, because sonic-cfggen loads them in the left-to-right order they were specified on the command line, therefore providing flexibility for loading JSON files in a specific order. As long as init_cfg.json is specified before config_db.json, the values specified in config_db.json will take precedence.
* [dhcp-relay]: Add DHCP Relay Monitor (#3886)
DHCP relay MONitor (dhcpmon) keeps track of DORA messages. If DHCP Relay
is detected to be not forwarding DORA message, dhcpmon will log such event
to syslog. Under the hood dhcpmon keeps counts of clients DR messages,
forwarded DR messages, DHCP server OA messages, and forwarded OA messages.
dhcpmon will check every 12 sec (configurable) if counts are monotonically
increasing and record snapshot of those counters. dhcpmon will report
discrepancies when detected between current counters and snapshot counters.
