This reduces the need for the librdkafka system dependency and results in
statically linking librdkafka.a against the C extension.
There's a few hacks in extconf.rb specifically to deal with librdkafka's build
system, as well as apply checksumming to the downloaded file
Fixes#8
This adds a requirement for 1.8.7 clients to install the SystemTimer gem for
timing out on Hermann::Result#value(timeout) to block and timeout correctly
Fixes#25
Provided that /something/ is ticking the librdkafka reactor underneath, the
Hermann::Result will be updated with the message delivery status when that's
completed.
What's still missing is producer level error calbacks
