Retry for transient faults

[jeehwancho]

Is it supposed to handle transient faults like 504 by retrying, or have users handle?
It seems to me the fix could be as simple as using one of request wrappers like node-request-retry in place of request, for example.
Any thoughts would be appreciated.

They are left for the user to handle. The original code is generated from the Swagger Codegen project, so if you wanted to add that retry library, that would be the right place to add it (unless you can figure out a way to add it into this library w/o modifying the generated code in api.ts)

PRs welcome.
