Remove SCITRAN_RUNTIME_PROTOCOL

[ryansanford]

This variable was a temporary measure from #190 and never fully removed until now.

@nagem and @gsfr -- can you test in your respective environments please including bootstrap process? Thanks.

LGTM, my only question is the differences between sample.config and the DEFAULT_CONFIG in config.py. I'm curious why RUNTIME configs only exist in sample.config and if they are required to remain there or if setting SCITRAN_SITE_API_URL is enough. This might be more of a legacy question for @gsfr.

@nagem 6056ddf adds a comment regarding the RUNTIME vars. Essentially, they are only consumed by bin/run.sh for it to setup a standalone local instance hosted by paster, and not meant to be consumed by the API.

Let me know if that doesn't answer your question.

👍 Tested.
