openbao-monitor: remove non-json output of health and init commands

Remove the stdout from successful health and init commands.

The output of health command will be parsed by scripts.  The stdout for
init will be extra and not properly formatted for pod logs.

Partial-bug: 2117422

Test Plan:
PASS  inspection of stdout/stderr for health and init commands.
