Subject: [PATCH] enable copying vendor and using go build cache in Dockerfile

The docker ignore was ignoring vendor, and as a result, having to download a
lot of packages on each build. By letting those be copied over locally, we can
save a lot of extra downloading. Plus the build cache being saved between runs
saves time as well.
