Can not build docker images

[Gallardot]

Prometheus-Kafka-Adapter is a very good project that has helped us a lot. We made some improvements to it, so we need to rebuild the docker image.

But we're having some problems and we need some help.

This appears to be a version dependency issue with libssl.

The travis-ci has the same problem.

Yes, as stated here https://github.com/Telefonica/prometheus-kafka-adapter/blame/master/Dockerfile#L4 we included some edge versions, that is a risky practice. I'll send a fix as soon as possible, because that workaround is no longer needed.

Please consider contributing those improvements back to the community in one (or several) pull requests :)

@Gallardot #62 fixed a build error introduced at #59.

please use the latest master version if you want to use confluent-kafka-go 1.3.0

please try #63 version instead if you prefer confluent-kafka-go 1.6.1

thanks for using prometheus-kafka-adapter 🙂

Thank you for your help and quick response. I have tested the latest version and there is no problem. I will create a PR for our improvements later. Thanks again.
