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.
