Adds the magic `frozen_string_literal: true` comment to every file and
enables a Rubocop rule to make sure that it's always going to be there
going forward as well.
See here for more background [1], but the basic idea is that unlike many
other languages, static strings in code are mutable by default. This has
since been acknowledged as not a particularly good idea, and the
intention is to rectify the mistake when Ruby 3 comes out, where all
string literals will be frozen. The `frozen_string_literal` magic
comment was introduced in Ruby 2.3 as a way of easing the transition,
and allows libraries and projects to freeze their literals in advance.
I don't think this is breaking in any way: it's possible that users
might've been pulling out one of are literals somehow and mutating it,
but that would probably not have been useful for anything and would
certainly not be recommended, so I'm quite comfortable pushing this
change through as a minor version.
As discussed in #641.

Moves away from Committee and towards stripe-mock, an external
self-contained executable API stub server based on OpenAPI [1]. The
motivation here is that instead of making stripe-ruby a special
snowflake, we can use a single well-tested and feature-rich mock
implementation to drive every API's test suite.

See [1] for details, but a few conventions changed around the structure
of the OpenAPI repository and the data within the fixtures file. Here we
put in some minor changes to compensate for them.

Naming a directory `spec` in a Ruby project is terribly ambiguous. This
clarifies the purpose of this directory and makes it easier to find if
you know that you're looking for OpenAPI.
I'd originally added this class for the first stub pass that used
OpenAPI because I thought we'd need the ability to finetune some of our
stubbed responses. It turns out that we've been able to get away without
it so far so I'm removing it for now. This commit can be reverted if it
turns out that we need it back later.
Adds some testing infrastructure that reads in the OpenAPI spec and its
fixtures. These changes will allow us to starting porting over each of
stripe-ruby's test suites.
