* Fix context for the showWarning function

If the difference between the current time on a client and time on a server is quite big, Prometheus tries to show a related warning in UI on the Graph tab. But in the code, an incorrect context is used to invoke this method. As a result, an error is showed in the web developer console and the whole page stop working at all. This commit fixes the context.

* Added query logging for prometheus.
Options added:
1) active.queries.filepath: Filename where queries will be recorded
2) active.queries.filesize: Size of the file where queries will be recorded.

Functionality added:
All active queries are now logged in a file. If prometheus crashes unexpectedly, these queries are also printed out on stdout in the rerun.

Queries are written concurrently to an mmaped file, and removed once they are done. Their positions in the file are reused. They are written in json format. However, due to dynamic nature of application, the json has an extra comma after the last query, and is missing an ending ']'. There may also null bytes in the tail of file.
