Correctly handles the instance domain metrics now, some regexs
had a extra space at the end which wasn't in the data file, do
the proc metrics more efficiently by splicing the array during
reading to match the expected fetch direct-array-offsets, add
more diagnostics, and finally add timestamps metrics showing
the date/time of last read on the tailed data files.
Improvements and fixes to the Zimbra PMDA.
