Extraneous "Connected/Authenticated" output on AWS Render

[aparrapo]

Running any render job on AWS produces extraneous connection/authenticated messages (see the ones logged by transport.py).

These are caused by running commands over SSH, which is done in the scripts/aws/create.py run_ssh_command function. We wish to silence that output.

Steps To Reproduce

1. Ran

   python3 scripts/render/run.py --flagfile res/flags/run.flags

   Where res/flags/run.flags is:

   --alsologtostderr=1
   --stderrthreshold=0
   --log_dir=~/logs
   --project_root=s3://facebook360-dep-sample-data/room_chat/50_frames
   --cache=/Volumes/cache
   --csv_path=~/Downloads/accessKeys.csv

2. Clicked on "Run" on the depth estimation tab with default values except first=000100 and last=000105.

Describe what you expected to happen:

No extraneous output being produced
