* [sflow + dropmon] added INCLUDE_SFLOW_DROPMON flag, added patches for hsflowd
*Added a capability of monitoring dropped packets for the sFlow daemon in order to improve network - monitoring, diagnostic, and troubleshooting. The drop monitor service allows the sFlow daemon to export another type of sample - dropped packets as Discard samples alongside Counter samples and Packet Flow samples.

* Updating version of hsflow daemon to apply
fix, which resolves problem of switching
between IPv4 and IPv6, in case when the
IPv4 has deleted for the interface.
The new release of hsflowd contains the fix for the issue: sflow/host-sflow@2703ecb
How I did it
HSFLOWD_VERSION env variable has changed in the rules to be pointed to the latest release of hsflowd.
How to verify it
sudo config sflow enable
sudo config loopback add Loopback1
sudo config int ip add Loopback1 a84f:97ff:fea7:33a5::fe80/64
sudo config int ip add Loopback1 192.168.101.1/24
sudo config sflow agent-id add Loopback1
sudo config sflow collector add Collector1 192.168.101.1
sudo config sflow collector add Collector2 a84f:97ff:fea7:33a5::fe80
use sudo sflowtool -p 6343 -l for checking sflow data
remove and add again the ipv4 entry of Loopback1.
hsflowd should change agent ip from IPv4 to IPv6 and wise versa, depending on IPv4 entry present or not.
Switching between IPs is being performed by hsflowd, based on IP address priority ranking.

* Bump version number to 2.0.32-1 to include a fix for a memory-leak
found during testing. A wrong API is used to free the cJSON
data-structure, which only frees the first pointed-to structure.
The proper API should recursively free all structures.

- build SONIC_STRETCH_DOCKERS in sonic-slave-stretch docker
- build image related module in sonic-slave-buster docker.
This includes all kernels modules and some packages

As per SONiC CLI requirements, we wanted the collector port to default to 6343 if not explicitly configured. In the Click based CLI, if the collector port is omitted, the port will be set to 6343 by default (https://github.com/Azure/sonic-utilities/blob/master/config/main.py#L2543).
However, if sonic-mgmt-framework based CLI is used, hsflowd was using port 0 as default. host-sflow v2.0.26-4 addresses this issue (i.e. use 6343 in case “collector_port” is not set).
Upgrade hsflowd to v2.0.26-4 to pick up https://github.com/sflow/host-sflow/releases/tag/v2.0.26-4.
Introduce a new "sflow" container (if ENABLE_SFLOW is set). The new docker will include:
hsflowd : host-sflow based daemon is the sFlow agent
psample : Built from libpsample repository. Useful in debugging sampled packets/groups.
sflowtool : Locally dump sflow samples (e.g. with a in-unit collector)
In case of SONiC-VS, enable psample & act_sample kernel modules.
VS' syncd needs iproute2=4.20.0-2~bpo9+1 & libcap2-bin=1:2.25-1 to support tc-sample
tc-syncd is provided as a convenience tool for debugging (e.g. tc-syncd filter show ...)
