Use Docker multi-stage build to start stx-oidc-client image from
'scratch' after using the upstream go image as builder.
Build the stx-oidc-client executable as statically linked.
This commit removes the build image and module downloads which are
approximately 500MB. Instead of those artifacts take a snapshot of the
go version and downloaded file list.
Test plan:
PASS: build image
PASS: sanity on isolated executable
PASS: inspect image content/size
PASS: application sanity; authenticate and run kubectl command, review
