While doing CLI changes for SNMP configuration, few changes are made in backend to handle the modified CLI.
** Changes**
- "community" for "snmp trap" is also made as "configurable". snmpd_conf.j2 is modified to handle the same.
- Changed the snmp.yml file generation from postStartAction to preStartAction in docker_image_ctl.j2 specific to SNMP docker, to ensure that the snmp.yml is generated before sonic-cfggen generates the snmpd.conf.
- Changed to make the code common for management vrf and default vrf. Users can configure snmp trap and snmp listening IP for both management vrf and default vrf.
* [SNMP] management VRF SNMP support
This commit adds SNMP support for Management VRF using l3mdev.
The patch included provides VRF support, there is no single
"listendevice" configuration, rather multiple agentaddress
config options can each have their own "interface" to bind to
using "ip%interface". The snmpd.conf file is accordingly
generated using the snmp.yml file and redis database info.
Adding below the comments of SNMP patch 1376
--------------------------------------------
Since the Linux kernel added support for Virtual Routing
and Forwarding (VRF) in version 4.3
(Note: these won't compile on non-linux platforms)
https://www.kernel.org/doc/Documentation/networking/vrf.txt
Linux users could not use snmpd in its current form to
bind specific listening IP addresses to specific VRF
devices. A simplified description of a VRF inteface
is an interface that is a master (a container of sorts)
that collects a set of physicalinterfaces to form a
routing table.
This set of two patches (one for V5-7-patches and one
for V5-8-patches branches) is almost identical to patch
single "listendevice" configuration. Rather, multiple
agentAddress config options can each have their own
"interface" to bind to using the <ip>%<interface>
syntax.</interface></ip>

This is a follow-up of sonic-snmpagent PR 92
Now that licensing issues have been solved FRR is distributed with SNMP
support compiled-in. This PR adds the last bits of configuration to get
the frr-snmp debian packages added to the docker container and the
config bits to enable the snmp module in FRR
This PR brings the functionality of being able to poll bgpd for routes
and peer status.

Modify minigraph parser output format so it fit DB schema
Modify configuration templates to fit new schema
Systemd services dependencies are modified so database starts before any configuration consumer
Add a sonic-config-engine to help generate config file based on minigraph and other data on runtime. Modify fpm, teamd, lldp, snmp, and platform-monitor docker to use sonic-config-engine to generate config in docker upon load.
