Rebuild docker container to patch for CVE-2019-14697

[thomasv314]

#230 incremented the base version of Alpine from 3.7 to 3.10 to patch CVE-2019-14697

https://hub.docker.com/r/jtblin/kube2iam is still built from the Alpine 3.7 base

Would it be possible for an updated image to be built and pushed to docker hub?

@jtblin is there some regular issue/PR grooming going on or is there someone we can ping on issues like that ?

@thomasv314 you can build your own (steps by @uthark)
