Answer 1

You can Set message type property as follows.

<property name="messageType" value="multipart/form-data" scope="axis2"/>

So it will invoke the multipart/form-data formatter and send out as a multipart/ form-data message.

Answer 2

You can use builder mediator(https://docs.wso2.com/display/ESB481/Builder+Mediator) for this purpose. Builder mediator will build the message within WSO2 ESB such that the message is converted to the desired Content-Type.
