Process non-prefixed forms of all config settings [#9]
Trying to guess in advance which part of the config a user will put in
the `settings` section and which they'll put in `environment` is a
fool's errand. Just let everything go in either place.

The ServiceAccount field only had an `envconfig` tag (as opposed to
`split_words`) because that triggered envconfig to look for the non-
prefixed form. Now that we're finding non-prefixed forms of everything,
we can use the clearer/more concise tag.

Note that TestPopulateWithConflictingVariables isn't meant to say
"here's what behavior we *want*" so much as "here's what the behavior
*is*." I don't think one thing is any better than the other, but we
should know which one we're getting.

Use a plain string for helm.Config.Command [#9]
I'm leaving the no-op test file in place because my next step is to add
new behavior that will require testing.

Rename Delete to Uninstall [#4]
Helm3 renamed its delete command to uninstall. We should still accept
helm_command=delete for drone-helm compatibility, but the internals
should use Helm's preferred name.

Extract Plan's InitKube creation [#4]
It's `func initKube` rather than `var initKube = func` because initKube
is not meant to be returned by determineSteps.

Instantiate a Delete when appropriate [#4]
"delete" would be a more natural name for the instantiation function,
but that's a reserved word in golang.

Initialize kubernetes config on upgrade
This change revealed more about how the system needs to work, so there
are some supporting changes:

* helm.upgrade and helm.help are now vars rather than raw functions.
    This allows unit tests to target the "which step should we run"
    logic directly by comparing function pointers, rather than having to
    configure/prepare a fully-valid Plan and then infer the logic’s
    correctness based on the Plan’s state.
* configuration that's specific to kubeconfig initialization is now part
    of the InitKube struct rather than run.Config, since other steps
    shouldn’t need access to those settings (particularly the secrets).
* Step.Execute now receives a run.Config so it can log debug output.

Implement the debug flag and help command
I'm vacillating about the choice to have separate Config structs in the
`helm` and `run` packages. I can't tell whether it's "good separation of
concerns" or "cumbersome and over-engineered." It seems appropriate at
the moment, though.
