feat: use additional volume for upload logs

• d741e1b chore: vary base mount point for striped volume

  I want to use this role to mount a volume on the uploaders too, so the base mount point may be
  different.

  I renamed the role to something a bit more specific that I think captures the purpose.

  I've also taken out a role being applied to the playbook that formatted a disk if we were using AWS
  as the provider. We will hopefully move to AWS soon, but for the time being this was causing a bit
  of confusion and I don't think it will be used; we'll probably need the striped volume setup for AWS
  too.

• ed609e7 chore: apply retries for service restarts

  I've seen these fail during deployments and unfortunately they will cause the workflow run to fail.

  A simple restart should prevent the failure. These have been applied to other service restarts that
  fail occasionally and they seem to work.

• 6f5d955 feat: use additional volume for upload logs

  If we want to launch testnets with extended and verbose logging for uploads, we will run out of disk
  space very quickly. For this reason, we will use an additional volume and have the upload logs
  output here.
