pulsar.Client() needs option to supress STDOUT

**Is your feature request related to a problem? Please describe.**
This isn't necessarily a problem, but requires a workaround

**Describe the solution you'd like**
Simply add
client = pulsar.Client(ip, stdout=False)

**Describe alternatives you've considered**
Otherwise I have to manually supress stdout when I call pulsar.Client() or producer.send()
