warn user if an ORM is not installed, but footprints are enabled

[tjwebb]

If no ORM is installed but config.footprints.models is configured, then FootprintService will likely not exist and the footprint routes will crash.

Maybe this can be done under trailpack-router instead of hapi/express/koa.... ?

[jaumard]

It can be done under validate method of trailpack-footprints

Does this mean we can close this issue w/r/t trailpack-hapi?

[weyj4]

@jaumard can we close the issue?

[jaumard]

If we move the issue on another repo yes. There multiple choice for this :

trailpack-router can check this, warn user and ignore routes to not have crashing routes
or
trailpack-footprints can check this and warn user, but routes will crash
