Have a simple way of showing logs

[bravomartin]

It's hard to find the logs for a task, which become specially necessary when running tasks (as opposed to actual user-facing routes). In the case of animal, for example (and on AGAC in the future) it would be useful to have some way of showing progress to the user, instead of calling us when something doesn't work as expected.

Possible ideas:

• have a command to open the appropriate lambda logs url
• have a simple secondary lambda that displays the logs on the browser and optionally refreshes every ~5 seconds. maybe protected with some simple secret?
