upgrade mysql_async from v030.0 to v0.31.2 to fix parse errors

Summary:
D50506429 upgraded mysql_async to v0.30. With that version of the crate, the asic license_monitor stopped working with the following error:

```

```

Unfortunately, the change logs and issue tracker on github are not clear. [mysql_async v0.31.2](https://github.com/blackbeam/mysql_async/releases/tag/v0.31.2) addressed this [issue](blackbeam/mysql_async#219) despite what the comments say. Both that issue and the release refer to a  conversation on [glitter](https://matrix.to/#/!rVBiivVGEBsRPFFerK:gitter.im/$CkNiRgwTwUthqxdYM5khT12BJ3pLxfSZC0CCfbMANQo?via=gitter.im&via=matrix.org). Putting the pieces together, this issue was addressed by that release.

I tested the license_monitor with mysql_async v0.31.2 and the issue went away.
