by using @utils.log_method decorator or log.debug().
Some commands have no logging.
This commit calls a logger in the base class and
drops all logging definition from individual commands.

that abstracts away the logging capability and unifies it behind
a common function instead.

Create a `configuration show` command that displays the current
configuration of the CLI. Different configurations can be
displayed using options such as --os-cloud. Passwords and
tokens are redacted by default unless the --unmask
option is specified.
