Update kafka 10 to newer alpine #289

Motivation - current version doesn't use /etc/resolv.conf which prevents kubernetes usage with the current image. See gliderlabs/docker-alpine#8

TBH - we plan to switch to the openjdk alpine image (something like #290) - so this shouldn't be required.

@sscaling would you prefer that I will switch to openjdk alpine image ?

I'm saying that PR #290 supersedes this PR. So if we merge that, this can be closed.

@YonatanKiron PR #290 is merged. Does this fix your issue?

@sscaling Not really if it doesn't build older versions.
See I'm using wurstmeister/kafka:0.10.0.0, so if you can rebuild the images somehow so it will actually take effect on the images that would be amazing

@YonatanKiron - we're trying to position the current master branch so that we can hopefully unify master and release branches. This issue was raised a while ago: #163

Then, yes I think it will fix my issue!

Why have you removed mirror selection?

Actually because 0.10.0.0 doesn't exists there (Take a look at http://apache.spd.co.il/kafka/)

closer.cgi just rotates through the various mirrors closest to you. So if a particular mirror doesn't have the requisite version of kafka, then retrying should eventually result in a mirror that does have the version.

To be true, it doesn't exists in my region but I see what you are talking about

Perhaps there's a better technique / algorithm to employ here? Or just make it user overridable - such as EXPLICIT_KAFKA_DOWNLOAD_MIRROR or similar?
