Description

This PR adds a new ExtractIR job and supports it in the CLP package. The change is a preparation for LogViewer support.
The IR extraction job takes 3 arguments: original_file_id, msg_ix and ir_target_size. The query scheduler use the first two arguments to find the file split to decompress, and creates a single task to extract the IR into a local path specified in the clp-config.

The PR makes the following changes:

1. Adds a new job type, ExtractIR and support it in the query scheduler
2. Refactors query scheduler to let IR extraction job and search job share common code
3. Add a new worker task extract_ir_task. Refactor the search task to let share common code with the new task.
4. Updated start-clp.py to let different type of workers have specific mounts and enviroment
5. Add IR extraction related configs into the clp-config.

Validation performed

• Submitted an IR extraction job with a helper scripts, confirmed that job finishes successfully and an IR is extracted.
