Task deploy:setup occasionally fails when deploying to brancher nodes acceptance environments

[pieterbeens]

We're using Hypernode Deploy together with Hypernode Brancher so that we have automated acceptance environments for every feature branch / PR. In general this works great, but sometimes the "deploy to acceptance" step randomly fails at the deploy:setup task with the following message:

task deploy:setup
  [acceptance:hntestbrancher-ephz6dx5o.hypernode.io] run mkdir -p ~/apps/hntestbrancher/shared
  [acceptance:hntestbrancher-ephz6dx5o.hypernode.io] ssh: Could not resolve hostname hntestbrancher-ephz6dx5o.hypernode.io: Name or service not known
  [acceptance:hntestbrancher-ephz6dx5o.hypernode.io]  error  in setup.php on line 7:

This need to be fixed to get more predictable and repeatable CI/CD
