Jason Chang 32b59565b7 Refactor errors for sync command
Per discussion in go/repo-error-update updated aggregated and exit
errors for sync command.

Aggregated errors are errors that result in eventual command failure.
Exit errors are errors that result in immediate command failure.

Also updated main.py to log aggregated and exit errors to git sessions
log
