add plugin hosts to seperate plugins from gloomi

This adds a plugin host that seperates plugins from the gloomi process,
allowing for plugins to be unloaded and loaded. This commit also has a
fair amount of other changes, nice to haves and bug fixes, some notable
changes are:
- Highly available reverse proxy from my Flux project
- Improved gloomi functionality
