Feature - Add project Id for the /features route #102
Description
I'm using Growthbook Proxy to get feature information from the cache, but the project Id is missing on the response payload.
Also I can't filter features by it's project when I have features tied to a specific project.
This is important because in some situations I need to get dynamically all features from a specific project, then I iterate through then to do business logic.
Today my only options are: creating a specific SDK that have access to only one project or calling the Growthbook backend API to get all features filtered by project and then using Growthbook Proxy to get detailed information about each feature.
