This PR was originally intended to fix issue #81 by updating python cryptography version to the latest. However, python cryptography only provides pre-built wheels for amd64 and aarch64 platforms. Therefore, it is better to separate time-consuming docker build for arm/v7, so it can use pre-built packages from the alpine repo.
