Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Tests: refactored least_conn test. First, start long requests to busy both backends, and ensure that subsequent consecutive requests are balanced to the only backend with zero connections. This change aims to get rid of false negatives due timing issues.
