Closes https://github.com/woodpecker-ci/woodpecker/issues/1617 The `woodpecker exec` auto-detects the backend by iterating over a map of backends. However, since Go 1 the runtime randomizes map iteration order, so a random backend might be chosen during each execution. PR changes to auto-detection to iterate over the backends list with predefined priority: `docker`, `local`, `ssh`, `kubernetes`. --------- Signed-off-by: Alexander Matyushentsev <AMatyushentsev@gmail.com>
