By default, several environment variables are read to configure the client:
CLOUD_STORAGE_EMULATOR_ENDPOINT: if set, use this http endpoint to make all http requests instead of the production GCS service. Also, if set, the CreateDefaultClientOptions() function will use an AnonymousCredentials object instead of loading Application Default Credentials.
CLOUD_STORAGE_ENABLE_CLOG: if set, enable std::clog as a backend for google::cloud::LogSink.
CLOUD_STORAGE_ENABLE_TRACING: if set, this is the list of components that will have logging enabled, the component this is:
how to authenticate to the client. Using a nullptr for credentials results in undefined behavior.
channel_options
ChannelOptions
the configuration for SSL certificate validation.

static CreateDefaultClientOptions()
Creates a ClientOptions with Google Application Default Credentials.
If Application Default Credentials could not be loaded, this returns a Status with failure details. If the CLOUD_STORAGE_EMULATOR_ENDPOINT environment variable is set, this function instead uses an AnonymousCredentials to configure the client.
