**Description**

This adds a new field 'prefix' as discussed in #1639. tldr is that the
existing "version" field has been overused in various and confusing
ways. Notably for OpenAI, it was literally used for expressing the
prefix of the endpoints and not really a version in any sense.

**Description**

This commit adds an additional safeguard for older deployment regarding
the OpenAI prefix configuration added in #1666. More specifically, this
prevents an issue that could happen in a small window when the old
extproc is running while the extproc config gets updated by the new
controller.
