Description

The error log is often critical for understanding why a query failed and often contains critical information, e.g. Memory Limit Exceeded reports, scan node errors, etc.

We should include the error log in the thrift-encoded and pretty-printed runtime profiles so that it's easier to debug query failures from the profile.
