* gpperfmon alert log grows indefinitely in case of format issues

If there is a formatting issue in GPDB alert log, gppefmon would
constantly try to load the same errorneous data. It results in log
file growth beyond acceptable limits (gigabytes), which in turn
causes server OOM because loading process uses iconv on the whole
input file.
In case of broken entries we should just archive affected CSV file,
marking it as "broken" one, to avoid issue escalation

* Table definition for log_alert_now reads all the *.csv files from the logs directory, and broken files match this filter as well. Fixing by storing broken files without csv extension
