Our existing HTTP clients are built the right way, i.e. we're creating new clients with
&http.Client{}
and they have a timeout set, as opposed to relying onhttp.DefaultClient
which is shared and mutable. But in this pull request I'm proposing to use clienthttp because in addition to promoting non-global clients they come with good defaults for a couple of different scenarios: DefaultClient (for short-lived conns against arbitrary hosts) and DefaultPooledClient (for connection reuse against same hosts).
