experiment hosting and review policies - default accept or reject

[stephen-soltesz]

This issue is a note that current experiment hosting and review policies could be summarized as "default reject" because the maintenance of code and services constitutes a "shared responsibility" for M-Lab staff, so the bar for adoption is high.

• Procedure for approval of new experiments and allocation of slices
• M-Lab Experiment Developer Responsibilities, Requirements, and Guidelines

This is in contrast to other policies that could be "default accept" or that limit the "shared responsibility" due to how the system is managed or who has access to it, which taken together could lower the bar for adopting a new experiment or service.
