Add ccx_consumer_archive_size counter

[epapbak]

Description

• Refactor StatsWatcher to cache archive type and size for each receive archive
• When archive is downloaded, the size of the extracted archive is cached
• When the archive is extracted, the type of archive is determined and cached
• ccx_consumer_archive_size counter is updated when the above information is available for an archive

(I made it this way to not touch the ocp_engine.py file, which we might remove in the future)
