Updates to the api docker image
Updates to the api docker image

* Changed the base api to run on Centos 7 rather than 6.
* Installed make since this is needed for some packages
* Installed node-gyp globally rather than letting it install as a
dependency.  This resolved build errors with multiple packages to
include bcrypt and the pdf package
