It fails on AWS, need to figure out if it's transient failure or not. While I was there, found lots of small bugs when endpoint is unresponsive, or target nodes are unresponsive and fixed them. In retry formatting added `\t` so that embedded errors are better aligned in the output (same as multierror). Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
