Bug: Alpine Dockerfile Issues

[naphelps]

Describe the bug.

1. The base image is version 3.7. This was last updated June 19, 2019. https://github.com/open-horizon/anax/blob/69bc5f7323ccba1dd35c9adb47f006b4ca54245b/anax-in-container/Dockerfile.alpine.amd64#L1

2. This Dockerfile references microdnf to work with packages, but Alpine Linux uses apk as its package manager. https://github.com/open-horizon/anax/blob/69bc5f7323ccba1dd35c9adb47f006b4ca54245b/anax-in-container/Dockerfile.alpine.amd64#L13

3. IBM is the labeled vendor. https://github.com/open-horizon/anax/blob/69bc5f7323ccba1dd35c9adb47f006b4ca54245b/anax-in-container/Dockerfile.alpine.amd64#L3
