using standard python base image

[yifanfu]

Recently the cryptography seems failed to build in apline version of python base image. I have replaced the alpine version of python with the standard (I believe it's Debian based) version of python base image, and all the builds passed.

[freyta]

It seems to work fine on my side. Can anyone else confirms that it doesn't work?

@freyta I'm also finding the Alpine image builds fine. The proposed changes in this PR would dramatically increase the image size. It also fails to link to a specific version of the python base image, which is against Dockerfile best practices as it would make the 7Eleven-Python image susceptible to future changes in the base image that may break it.

@yifanfu Could you please share some more information about what issue you're having with the cryptography build using the Alpine base image?
