As part of this commit, I upgraded the golang image used for building to
1.16 and consolidated how the docker-build rule was working. Previously,
it was failing in master's CI because the go modules were not downloaded
in the build image. To improve that, I replaced the combination of
docker run and docker build by a multi-stage Dockerfile responsible for
building the adapter and running it.
In addition to that, I removed the `_output` directory completely as it
wasn't really meaningful to have it anymore. I also removed the
`build-local-image` rule as it was a duplicate of the `docker-build`
rule with the only different of using a scratch base image.
Also, since all the base images that we are using by default are based
on busybox, I change the UID used in the image to 65534 which correspond
to the nobody user in busybox.

Travis seems to be having issues pulling deps, so we'll have to check in
the vendor directory and prevent the makefile from trying to regenerate
it normally.
This commit introduces advanced configuration. The rate-interval and
label-prefix flags are removed, and replaced by a configuration file
that allows you to specify series queries and the rules for transforming
those into metrics queries and API resources.
The `build` Makefile target attempted to place the generated artifact in
`/build`, where it should have used a local directory instead. This
commit makes the directory configurable using the `OUT_DIR` argument,
and defaults it to ./_output
The initial functionality works. There's still a number of TODOs to
clean up, and some edge cases to work around, and some errors that could
be handled better.
