title: Kafka Connect, JDBC connector password in clear text. How to avoid?
body: <p>I have a jdbc source connector that I'm using, and I've been using Postman to test and set this. The password for the db connection is in clear text, which is fine as long as I'm the only one seeing it. </p>
  
  <pre><code>    "config": {
          "connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector",
          "connection.url": "jdbc:db2://db2server.mycompany.com:4461/myDB",
          "connection.user: "dbUser",
          "connection.password": "DBPASSinClearText!",
          "dialect.name": "Db2DatabaseDialect",
          "mode": "timestamp",
          "query": "select fname, lname, custId, custRegion, lastUpdate from CustomerMaster",
          "timestamp.column.name": "lastUpdate",
          "table.types": "TABLE",
          "topic.prefix": "master.customer"
      }
  }
  </code></pre>
  
  <p>In production, the deployment team are the ones who set the config. Is there a way to encrypt this, so I don't have to share the clear text password with that team? </p>
