Write game logs async. Write messages in bulks.

[arielj]

This PR is a small refactor on how we write game logs to make the write async instead of inline before launching games.

This has a few benefits:

• games start launching faster since we don't wait for logs to be written
• if any issue happens while writing to logs, games start anyway

Also, with this change, appended messages are queued and written to disk at 1 second intervals instead of writing them immediately to disk, reducing the amount of writes we do.

Also, with this refactor, we can now include more logs in a single place (the initLog method), unblocking many issues related to adding more information in the logs.
