fix(Dockerfile): move to ubi-micro [OSD-8579]

the previous solution was ok, but the current one is more compatible
with the security team

- bump golang to latest (1.17)
- fix secuirty vuln found with 'trivy image scan'
- use ubi-micro to allow code-scanning using 'clair'
- did a 'go mod vendor && go mod tidy'
- gofmt a file using 'gofmt -w <filename>'
