Managing credential owner email in project.yaml

[christad92]

When a project is deployed to GitHub, we add the credentials and associate them with the owner of the credentials. While this is helpful to project collaborators to identify the owner of a credential in the project.yaml, we also expose identifiable information via GitHub, especially when the repo is public. This leaves us with a few options:

1. Mask the email address of the credential owner
2. Allow users to decide if they want the credential owner specified in the project.yaml
   athe ). If credential owner is required in the project.yaml, we should consider restricting Syncs to private repo.
