concerned.

ClientMetaClass (ABCMeta)
Client singleton metaclass.

- the singleton Client instance is created on first access to reflect the global configuration and local client configuration.
- the Client shouldn't be accessed from within pipeline steps (a warning is logged if this is attempted).
