Update Logging for Hyp3

[cmarshak]

Include logs to both standard err and to log directory for logging.

Specifically, these lines: https://github.com/ACCESS-cloud-based-InSAR/DockerizedTopsApp/blob/dev/isce2_topsapp/topsapp_proc.py#L81-L84

Per @jhkennedy suggestion:

• remove log files
• put into readme how to pipe logs into files for local docker runs

docker run -ti -v $PWD:/home/ops/topsapp_data topsapp_img \
               --reference-scenes S1B_IW_SLC__1SDV_20210723T014947_20210723T015014_027915_0354B4_B3A9 \
