To use this facility, the KVP user-space daemon (hv_kvp_daemon) has to be running. It reads the kvp_file when the host requests the guest to enumerate the KVP's. This reporter collates all events for a module (origin|name) in a single json string in the dictionary.

This should be done exactly once for the file indicated by KVP_POOL_FILE_GUEST constant above. This method takes a filename so that we can use an arbitrary file during unit testing. Since KVP is a best-effort telemetry channel we only attempt to truncate the file once and only if the file has not been modified since boot. Additional truncation can lead to loss of existing KVPs.
