This commit simplifies the way that compactions across a database's
keyspace occur due to reading the LevelDB internals. Secondarily it
introduces the database size estimation mechanisms.
Include database health and help interfaces.
Add database statistics; remove status goroutines.
This commit kills the use of Go routines to expose status throughout
the web components of Prometheus. It also dumps raw LevelDB status
on a separate /databases endpoint.
To achieve that, this PR
- converts static/index.html ("console") and graph to templates
- moved the handlebars template to separated file to avoid escaping issues
Route changes:
/status -> /
/static -> /console
/static/graph.html -> /graph
