Revert "torchx/runner: log events to torch.monitor (#379)" (#536)

Summary:
This reverts commit 4b989d5.

Importing torch.monitor adds a pretty large dependency on torch which hugely slows down load time in OSS.

This accounts for about 340ms of load time.

Pull Request resolved: #536

Test Plan: This isn't being used anywhere AFAIK so should be safe to land. Internal has a custom handler.
