Only *.py in modules are uploaded

[ooq]

This python program (https://gist.github.com/ooq/48c23aec420c682359d6a43cfc9cdd82) of mine throws Exception: [Errno 2] No such file or directory on remote but runs fine locally. Also it was working yesterday (was the runtime updated?) I suspect this could be a runtime issue because my local runtime uses a different boto3 botocore version.

I'm going to debug more today by trying these two things:

1. upload my runtime
2. pull the remote runtime and setup locally

Okay, problem identified. Boto3 will automatically detect certifi and use it for (maybe) some server authentication. This means that if certifi sits in my local env, Pywren will copy it to remote as a dependent module. However, certifi contains a bunch of .pem files that are ignored, as we only copy .py files:

files = glob2.glob(os.path.join(m, "**/*.py"))

This is why I'm getting the No such file or directory error, when certifi can't find those .pem files.

I'll push a quick fix that puts certifi on the preinstalled list.
We should rebuild the runtimes to include certifi (more security always seems better)

For:
files = glob2.glob(os.path.join(m, "**/*.py"))
A better approach is to include all files but exclude *.pyc files?
