Subject: [PATCH 1/2] I-P engine: Provide the option to store client data in
 engine ctx.

There can be some client specific data which could change from one engine run
to another. Adding a 'void *' data in 'struct engine_ctx' will be useful.
One such usecase is to provide a config option in ovn-controller to turn on or
off logical flow expr caching. And this config knob can be stored in the engine_ctx.
An upcoming patch will make use of this.
