[Feature] Recipe endpoint for private recipe should not be in the project but in the bundle

[khalid-s]

Hello everyone,

I am currently working with a couple of private bundles, each of them having their own private recipes repositories. For each recipe, we need to add an endpoint in the composer.json of the project and we currently have 5 of these. For each project we are currently specifying in their readme the different endpoints to add which is not most efficient.

I think that each private bundle should specify in its composer.json the endpoint to its recipe which would make more sense since it should be the bundle's responsibility to specify it's recipe.

There is currently a PR #952 on it, which is looking pretty good.

Cheers
