title: multiple Sequelize instances on single database
body: <p>I have few microservices using <strong>Sequelize</strong> as an ORM. 
  For simplicity I want all of then to share a single database even though they have nothing in common. </p>
  
  <p>I need each microservice to have:</p>
  
  <ul>
  <li>Its own Sequelize migration table so I can use rollback function safely.</li>
  <li>Each table needs a namespace according to microservice name. For example <code>ms1_table1</code>, <code>ms1_table2</code></li>
  </ul>
  
  <p>I havn't found anything relevant in docs or Google. Any idea or package for that issue?</p>
