return server_uris from mpc instance (#1912)

Summary:
Pull Request resolved: #1912

This change will return the server_uris dynamically based on what was passed in during instance creation. With D41204111 (d7114ca) to migrate MPCInstance from fbpcp to fbpcs, we don't need fbpcp release to make this change.
