credential validation for execution envs to allow only registry credentials to be associated with them, also adding security precautions for authfile and password, also combined token & password into one term to align with Quay, and added handling to account for users not filling in credential data and add a has_inputs function to simplify checking if the host, username, and password are present in the credential
