Allow SHOREMAN_CONCURRENCY to specify processes to be run (issue #7)

#7

Nice. I'm playing with removing the ruby dependency by using a bash associative array. This is what I've got so far:

declare -A proc_count

if [ -n "$SHOREMAN_CONCURRENCY" ]; then
  while read line; do
    proc="${line%%=*}"
    count="${line#*=}"
    proc_count[$proc]=$count
  done < <(echo $SHOREMAN_CONCURRENCY | tr ',' $"\n")
fi

get_concurrency() {
  proc="$1"
  count="${proc_count[$proc]}"

  if [ -z "$SHOREMAN_CONCURRENCY" ]; then
    echo 1
  elif [ -n "$count" ]; then
    echo "$count"
  else
    echo 0
  fi
}

I'll get it merged in soon.

Thanks for the help.

Thanks @statianzo quite a bit of bash I didn't know about, so I've learnt something. 👍

Would be nice if scaling here was done the same way as in the forego and logging-supervisord dokku plugins.
