WMS Logging

[gpotts]

At site they have added some nice logging for the ogc wms service. We need to try to OCR or type the domain WmsLog? domain object from site and integrate for easy metric reporting.

Add a crude GSD column for the table as well.

May want to think about this for other controller and services.

Please find attached an initial approach done at site.

Design Approach:

- Use Database Appender log4j if possible. We will make sure that the log4j populates the table properly.
- If the table is not populated will will use the site modification verbatim to capture the proper fields.

Unit Test:

- We will issue a WMS chip and verify that the chip is added to the WmsLog? table. To verify we can easily do either a grails groovy script to select or go into the database with psql and do a select clause ton the WmsLog? table.

We have added WmsLog?.groovy for the domain definition. We added WmsLogService? to help format the logging message. OgcController? now sends the logging parameters to the WmsLogService? and then does a log.info on thos paramters. The routed message is JSON. We have added to the config an Appender for log4j.
