Connector for Secret Manager

# This workflow demonstrates how to use the Secret Manager connector: # Retrieve a secret using three different methods # Expected output: the secret data (thrice) - init:  assign:  - project_id: ${sys.get_env("GOOGLE_CLOUD_PROJECT_ID")}  - secret_id: "test-secret" # Make sure you have this secret and it has a version of 1.  - version: "1" # Add data to an existing secret without base-64 encoding - add_version_string:  call: googleapis.secretmanager.v1.projects.secrets.addVersionString  args:  secret_id: ${secret_id}  project_id: ${project_id}  data: "a new secret" # Retrieve the secret in string format without base-64 decoding and assume # that the secret data is a valid UTF-8 string; if not, raise an error - access_string_secret:  call: googleapis.secretmanager.v1.projects.secrets.versions.accessString  args:  secret_id: ${secret_id}  version: ${version} # if not set, "latest" is used  project_id: ${project_id}  result: str_secret # Retrieve the secret in string format without base-64 decoding - access_secret:  call: googleapis.secretmanager.v1.projects.secrets.versions.access  args:  name: ${"projects/" + project_id + "/secrets/" + secret_id + "/versions/" + version}  result: base64_encoded_secret # Retrieve the secret using positional arguments in an expression - expression:  assign:  - secret_str_from_exp: ${googleapis.secretmanager.v1.projects.secrets.versions.accessString(secret_id, version, project_id)} - the_end:  return:  - ${str_secret}  - ${text.decode(base64.decode(base64_encoded_secret.payload.data))}  - ${secret_str_from_exp}
