WaitUntilTableExistsWithContext is an extended version of WaitUntilTableExists.
With the support for passing in a context and options to configure the
Waiter and the underlying request options.

The context must be non-nil and will be used for request cancellation. If
the context is nil a panic will occur. In the future the SDK may create
sub-contexts for http.Requests. See https://golang.org/pkg/context/
for more information on using Contexts.
