Replace `apk update` and `--update` flags with `--no-cache` across
Dockerfiles to improve consistency and eliminate unnecessary cache files.
This change reduces image size and ensures up-to-date package indices
without leaving temporary data. It also aligns with best practices
recommended for Alpine-based Docker images.
docker files need to be updated as go-builder is built on
golang:1.19-alpine3.16 so base image for netmaker/netclient
needs to be updated to apline3.16 as well
