This feature has been requested numerous times.  And it is not needed.
Really.  You have the management interface which can be done to resolve
exactly that problem.

- OpenVPN is configured with --management and --management-hold

- Start the management client script
  - polls for the OpenVPN management port to become available if it is not
    getting a connection instantly
  - once connected, it can do whatever queries/preparations needed
  - sends the 'hold release' command on the management inteface

- OpenVPN starts connecting to the remote server

And if OpenVPN looses its connection, the management interface can capture
that and do whatever it needs to do.  And if OpenVPN stops running/dies, this
management client script can even detect that and do whatever is needed in
this scenario as well - like restarting OpenVPN.

In fact - you can even *modify* the remote and proxy settings on-the-fly if
your management script figures that's even better.

Bringing up the "preconnect script" is just beating a dead horse.  That
feature is not remotely as powerful as what we already have in OpenVPN today.
