Remove or rename show_analysis flag from experiment results data

[mikewilli]

The show_analysis flag was originally used for local development to prevent accidentally breaking other people's workflows. It should no longer be needed, so we should try removing it. If there is some dependency on this flag that would break if it is removed, we should at least rename the flag to give more context on its use. The current name seems to imply that it is a generated field based on whether analysis is ready to be shown, but if we need to keep the flag for some reason it should be named something to indicate that it is static and/or that it is for local dev environments.
