c916572aca Update deps to Kube 1.11.3 
This updates the dependencies to Kube 1.11.3 to pull in a fix allowing
requestheader auth to be used without normal client auth (which makes
things work on clusters that don't enable client auth normally, like
EKS).

262493780f Clarify multi-metric queries 
The example on the multi-metric query was a bit misleading, so this
clarifies it a bit so it looks closer to a real-world example.

a1f4aab6d4 Restructure walkthrough 
This restructures the walkthrough to focus on the goal of scaling an
application from the start.  We start out with an application and an
autoscaler, and then walk through how we can make the autoscaler
actually able to function.

9f08038f07 Add a config walkthrough and update the readme 
A helful community member rightly pointed out that configuring the
adapter was a bit confusing, and a step-by-step example would be useful.
This adds such an example, and links to it from relevant places.

cfba614544 Remove extraneous /adapter from deployment args 
There was an extraneous `/adapter` in the deployment args that was
causing people issues.  This removes it.

9d7157f7cc Reduce metric namer label-GVR logspam 
It's fairly common to have a label pattern that matches lots of
irrelevant labels, so this makes the "error" about being unable to
normalize/resolve a label to a GVR a V(9) info log, instead of an error
log.

to an erroneus `as` clause.  This fixes that.

3fc2dbdf71 Explicitly build on tags in Travis

the vendor directory and prevent the makefile from trying to regenerate
it normally.

ec335c0777 Fix cross-compile typo in Makefile 
The makefile target for the output directory was hardcoded to $(ARCH),
independent of the actual target input in the makefile.  This fixes
that.

It probably eventually needs to be further modified with more specific
instructions about the Prometheus Operator.

eb6949c2a4 Explicitly mount /tmp as an emptyDir 
If using an image build with `FROM scratch` (as built by the
build-local-images make target), you need to explictly mount
/tmp as an emptyDir.

1e5cd68533 Makefile with actual deps 
This makes the makefile's build target have actual dependencies, so that
it only rebuilds any given adapter if that adapter's actual go files
have changed (yes, this is mostly redundant with Go 1.10, but it makes
working on read-only filesystems a bit nicer).

2984604be8 Advanced Configuration 
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.
