Logger no Longer Defaults to "debug" Log Level
Logger no Longer Defaults to "debug" Log Level

The logger utilized by the various Go applications comprising the
PostgreSQL Operator no longer defaults to a "debug" logging level.
Instead, by default the "info" logging level will be utilized (per the
default set by the Logrus logging package), and the "debug" log level
will now only be set if the 'CRUNCHY_DEBUG' environment variable is set
to 'true'.
