feat(logs): implement several filters & support retrieval of persiste…

…d logs (#165)

This commit does two enhancements to the `log` subcommand.

- add several options such as `--grep`, `--levels`, and `--regions` that allows for filtering out logs that we're not interested in
- add options called `--since` and `--until`, which enable the retrieval of persisted logs (as opposed to live logs)
