Title: Migration errors aren't recorded in web app logs (master)

If a migration fails, the agent can't boot, but it only logs the detail of the error to stdout, which is not ideal in a non-dev environment.

Acceptance Criteria
* Migration errors are logged at error level
* Failed operations are logged as a single message, but each separated by a new line.

Scope
* master branch
* see 276 for 1.5.x branch
