Binary size bot

The bot listens for Gerrit merges, receiving notifications via webhooks or directly via SSH client. When a merge is detected, it triggers an artifact fetch from COIN. The bot then extracts the artifact tarball and updates Influx databases with new file sizes. Files that can be monitored are specified in the configuration file.

usage: main.py [-h] [--configuration FILE] [--ssh]

options:
  -h, --help            show this help message and exit
  --configuration FILE  load configuration from FILE (default: config.json)
  --ssh                 Listen gerrit SSH stream (.ssh/config credentials required)
