What is the sessionMap.map files created under $lisatmp_dir?
These files are used to keep track of the IDs used in the REST APIs for Builder Sessions, Bundles, etc. in Virtualize Invoke v2.
We should not delete or mess with these files. The .map files aren't temporary and will remain in the file system even when DevTest services are not running.
The sessionMap.map.wal.N files are temporary and are used only while the services are running. They should go away when the services are shutdown normally.
