New workload: http_logs (1998 FIFA World Cup web logs) #10

Port the OSB http_logs workload. ~31 GB of web server logs; widely used benchmark across the search engine community. Time-series heavy, large-scale log workload complementary to eventdata.

⚠️ Prerequisite: Source data carries an HP copyright with a non-commercial restriction. Get legal clearance from ASF Infra/Legal before any work begins.

Tasks

• Obtain legal clearance
• Convert OSB workload using solr-orbit convert-workload
• Define operations: time-range queries, status faceting, bulk indexing
• Add 1k sample corpus for test-mode
• Check whether any operations belong in common_operations/ rather than this workload

Depends on: #3 (ASF dataset hosting must be resolved before corpus files can be finalised)
