During install, wait for MySQL to start, instead of sleep

[martinmosegaard]

This issue tracks a TODO in staciFunctions.f / installStaci in this code:

  if [ ! -z $start_mysql ];then
    # TODO: Need to wait for MySQL to start, before continuing, instead of sleep
    sleep 20

Inspiration from a mongodb container:

#!/bin/bash

attempt=0
while [ $attempt -le 59 ]; do
    attempt=$(( $attempt + 1 ))
    echo "Waiting for server to be up (attempt: $attempt)..."
    result=$(docker logs mongo)
    if grep -q 'waiting for connections on port 27017' <<< $result ; then
      echo "Mongodb is up!"
      break
    fi
    sleep 2
done
