Add temp solution to get certs for pc_instance cert providers (#1833)

Summary:
Pull Request resolved: #1833

This is just an intermediary solution for allow us to test tls data distribution from stage service to onedocker containers. After we build data transmission from PC Service via PC Instance repo, we will replace the implementation here with actually getting the certificates from pc_instance.
