Redirect getistio.io/download to tetrate.bintray.com/getistio/download.sh

[mathetake]

bintray is kind of a implementation detail of getistio, so I would like to redirect getistio.io/download to the download load script located in bintray tetrate.bintray.com/getistio/download.sh so that users can download getistio as follows:

curl -sL https://getistio.io/download | bash

This is similar to what Istio does with istio.io/downloadIstio where they redirect it to https://raw.githubusercontent.com/istio/istio/master/release/downloadIstioCandidate.sh.

FWIW, getenvoy also does the same thing: https://github.com/tetratelabs/getenvoy.io/blob/master/site/static/_redirects#L1

I have no objection in this proposal. We can do this. If everybody's on board, I can change the link while I'm working on the homepage as we speak.

Btw, this makes sense, for example, Bootstrap also had download button that allows the webiste visitor to directly download their zip file.

agree - please proceed - we'll update the download pages after the completion.

I see that there's already a content on /download path so we could do /downloadGetIstio just like Istio does. Either /downloadGetIstio and /download looks fine to me
