Description
Fixes #9193
Followup to #8972
This PR restores
vtctl VExec
functionality. It was removed based on the assumption the only uses for this command were for Online DDL command. This was wrong, and VExec is also used as a wrapper around VReplication.For now, we restore the full functionality, although we intend to deprecate use of VExec for Online DDL. See some discussion in #8972
