## Summary:
Steve pointed out (#73) that having genqlient with no arguments silently
use a default config file was a bit confusing, and changed it to use
`genqlient.yaml` by default (#74). Mark pointed out (#76) that this
makes it a bit less convenient when you're starting from scratch; you
have to go create a config file. In this commit I add a new init flag
that creates you a config file before using it.
Originally the suggestion was to use subcommands, e.g. we'd have
`genqlient init` and `genqlient generate` and so on. But I couldn't
think of anything else we might want subcommands for in the future, and
it felt a little silly to make you type `generate` each time. So
instead, I made it a flag, which has the nice property that you can do
`genqlient --init` and it will generate and then use a config file. (I
mean, maybe it will immediately crash because you don't have a schema,
but hopefully that's still a useful clue as to what to do next!) The
implmentation was fairly trivial.
Since we now have a nice way to generate a default config, I removed the
default values for most of the options; I've always felt they were
probably more confusing than helpful. (And indeed, all the users I know
of (Khan/webapp, and the much smaller project Steve was working on, are
setting those options explicitly.) This required a slight change to
the syntax to say "don't use context", which is probably also net clearer.
I decided this is also a good time to pull in a proper CLI parser (#31);
see ADR-504 for more on that choice. This also adds some nice help
messages!
Fixes#76, #31.

## Summary:
ContextType is in use at Khan as a part of our ka-context system; it
basically just lets you configure the type to pass as the `ctx` argument
to genqlient helpers (or say to omit such an argument). ClientGetter I
wrote thinking we might use it; then we didn't (because we have a few
different clients we may use) but it's not much code and may be helpful
to others. In this commit I clean up, document, and add tests for both
options.
The cleanup is mainly for ClientGetter, which was kind of broken before
because it was a Go snippet but couldn't specify imports. I was
thinking maybe you want to be able to write `ctx.Something()`, but I
just don't see how to make it work, so I made it a function of context,
which is probably the better idea anyway.
Additionally, I improved the documentation for both, and added tests for
those and several other config options that weren't completely tested.
Fixes#5.
