Enable container_expiration_policies with Graphql

backend-weight2

Overview

This is the initial step in enabling Graphql for the package stage.

The project api is currently set up to allow creation and updating of a given project's container_expiration_policy. The goal of this issue is to expand that same functionality to the graphql project api.

There are possibly two steps here:

1. Enable the project graphql resource to allow container_expiration_policy
2. Migrate the front end to use graphql instead of the rest API
