Added getJobLogs method which returns reverse sorted jobLogs for a jobHistory with an offset (for pagination) and number of records (needs to be limited as logs can be really log... aka: you don't want all that on the client memory)
Added getJobLogs method which handles defaults on the offset and the number of records returned
Wired getJobLogs method as a GET method
Defined an AJAX method for getJobLogs GET service
