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.

Follows the path established in 2d75c8f by porting the rest of
stripe-ruby's tests over to OpenAPI. There are a few other changes here
where I've removed some tests that are duplicated or don't make much
sense, or reorganized how we test certain things, but this commit is
largely the same migration operation applied in bulk a few dozen test
suites.
Introduce a `#save_with_parent` flag that allows the default behavior of
never saving API resources nested under a parent to be overridden, a
feature that we so far only know to need for updating a source under a
customer.
* Rename the `Update` operation to `Save`
* Add the `update` class method to all saveable resources
* Add tests for update method
* Add tests for plans, invoice items, and application fees
Usage on a top-level collection:
```
Stripe::Customer.list.auto_paging_each do |customer|
puts customer
end
```
Usage on a subcollection:
``` ruby
customer.invoices.auto_paging_each do |invoice|
puts invoice
end
```
We've also renamed `#all` to `#list` to prevent confusion ("all" implies
that all resources are being returned, and in Stripe's paginated API
this was not the case). An alias has been provided for backward API
compatibility.
Fixes#167.
Replaces #211 and #248.
This commit adds `Customer#create_subscription`, which allows a
subscription to be created on a customer without first fetching the
customer record.
Previously:
```
customer = Stripe::Customer.retrieve('cus_abc123def') # GET request
customer.subscriptions.create(plan: 'cool-plan-1') # POST request
```
**No alteration has been made to the above method; the preceding
implementation still functions as it did previously.**
With `#create_subscription`:
```
customer = Stripe::Customer.new('cus_abc123def') # No request
customer.create_subscription(plan: 'cool-plan-1') # POST request
```
This method removes the initial `GET` request and instead issues a
`POST` directly to create the subscription.
