This change removes plugins from Spyglass and places them in separate
repositories. Formation, a proprietary plugin, will be removed by this
change and Tugboat will become its own OpenDev maintained repo,
spyglass-plugin-xls. By creating more streamlined plugin management,
end users should be able to more easily create their own plugins for
different data sources.
