Merge #104 from dev

[SreeeS]

Summary

Merge from dev to master branch

Make release is failing on amazon-ecs-agent when we update the submodules.

The Error message is:

GOOS=linux CGO_ENABLED=0 go build -installsuffix cgo -a -ldflags "\
     -X github.com/aws/amazon-ecs-cni-plugins/pkg/version.GitShortHash=a04bd6ec \

	Use -buildvcs=false to disable VCS stamping.
make: *** [Makefile:40: bin/plugins/ecs-eni] Error 1
make: *** [build-ecs-cni-plugins] Error 2

This change is to include -buildvcs=false flag to the go build in Make file.

This error occurred after we updated the amazon-ecs-cni-plugins sub module in amazon-ecs-agent to pull the latest commit due to this change in golang: golang/go#37475

Implementation details

Added -buildvcs=false flag in Make file.
-buildvcs=false excludes version control information when golang version is >= 1.18.

Testing

make unit-test
make release on ecs-agent repo for go version 1.18.8 and 1.15

New tests cover the changes: no

Description for the changelog

bug-Fixed failed make release on ecs-agent repo
