Copied from the v4 tests: https://gitlab.com/gitlab-org/gitlab-ce/blob/v9.2.0/spec/requests/api/deploy_keys_spec.rb#L110-116

The v3 API documentation claims that `can_push` is supported when
adding a deploy_key.

https://gitlab.com/gitlab-org/gitlab-ce/blob/8-16-stable/doc/api/deploy_keys.md#add-deploy-key

Here we make good on this promise by adding `can_push` as an optional
parameter so grape can route it.

This was copied from the v4 API.
