Add cert bundle

After doing a migration on the server to HTTPS (this was more difficult than I expected because we also changed how our db works), I discovered that requests cannot validate our certificate for some reason. This is odd because my browser correctly validates that I am talking to server.iclab.org.

Regardless, I added our CA bundle (this is the certificate chain from GoDaddy and does not contain any private keys) and had requests use this bundle to validate the connection. I can confirm with testing that I can successfully upload to server.iclab.org.

While we wait on code review, I reverted back to the old server, so everything is still HTTP

@gsathya, will you review this? I can't push the update/ switch to HTTPS without this added verification.
