Linux PMDA fd leak metric

[David Disseldorp <ddiss@xxxxxxx>]

Hi,

The following patch adds a proc.fd.numopen metric to the Linux PMDA,
using the contents of /proc/<pid>/fd as its data source. This metric may
be useful in watching for application file descriptor leaks.

Feedback appreciated.

Cheers, David
