[bug] Incorporate Adapter Version # at buildtime

[mgfeller]

Description

build-args main.version=$VERSION and main.gitsha=$GIT_COMMITSHA are not being picked up.

Expected Behavior

when testing locally e.g. building using
GOPROXY=direct GOSUMDB=off go build -ldflags="-w -s -X main.version=VERSION -X main.gitsha=GIT_COMMITSHA" -a -o ./meshery-consul .

and running ./meshery-consul

expected result of grpcurl --plaintext 127.0.0.1:10002 meshes.MeshService.ComponentInfo is

{
  "type": "adapter",
  "name": "CONSUL",
  "version": "VERSION",
  "gitSha": "GIT_COMMITSHA"
}
