error reporting could be improved

[karenetheridge]

Every so often I encounter an error when submitting a report via App::cpanminus::reporter (presumably something transient on the network?) and it looks like this:

Error while sending this report, continuing with the next one (Test::Reporter: error from 'Test::Reporter::Transport::Metabase:'

looking at Metabase/Client/Simple.pm line 129, it would seem that we could improve this diagnostic by printing the actual HTTP response code, and some portion of the message body as well.
