  rest_client: Fix handling for async timeouts

This patch improves all rest_client async operations such that they
now correctly time out after the minimum between:

* the "rest_client.curl_timeout" modparam (seconds)
* the async() statement timeout, if any (seconds)

async: Add support for module-injected timeouts

In some cases, the module may have its own timeout for the async
operation which it would prefer to force into the reactor wait loop,
possibly even have it combined with the async(..., X) statement timeout
as well, with the minimum of the two timeouts to win out.
