Feature Request

Is your feature request related to a problem? Please describe:

Now, when executing a SQL statement through DM, we can't identify it whether from DM in the downstream easily. Only use the connection ID is a little hard.

Describe the feature you'd like:

two steps to achieve this:

1. embed DM version info in SQL statement as a comment
2. show the comment in the downstream

in DM, we can do step.1 to convert SQL statement like

/* ApplicationName=DM v1.0.0-alpha-g3f4c0d8 */ INSERT INTO db.tbl VALUES (1)

Describe alternatives you've considered:

another method to achieve this is making compare connection ID easier.
