RPi packages should ship ARM version of Mattermost
Noticed while handling !3401 (merged) - we are shipping Mattermost's amd64 version in our RPi package. From a quick glance, Mattermost doesn't provide official binaries for ARM so if we want to provide Mattermost as part of RPi package, we will have to build it from source (as opposed to the current strategy where we are using the upstream's compiled binary).
We should also think about if we want to ship Mattermost in an RPi package- being a low power device whether anyone is enabling such additional services or not.
