According to Sergey Belous it may be caused by the following commit (which we have in 9.1):

    Don't load DNS integration in l3_router_plugin

    In this patchset we stop the l3_router_plugin from loading the DNS integration
    extension. The DNS integration extension should only be configured by the
    operator by adding 'dns' to the 'extension_driver' list in ml2_conf.ini

    (cherry picked from commit 56962922cc439409bcecd808a1e9bbec2c3756f7)

In other words, this very extension was enabled by chance prior to 9.1. Instead operators are expected to explicitly enable it in ml2_conf.ini. Now that we've fixed this in 9.1, it affects mixed 9.0/9.1 environments.

The workaround is to explicitly enable this extension on all controller nodes.
