//Fast test for checking reassembly logic for split log by CRI-O.
//CRI-O split long string on parts. Part marked by 'P' letter and finished with 'F'.
//Example:
// 2021-03-31T12:59:28.573159188+00:00 stdout P First line of log entry
// 2021-03-31T12:59:28.573159188+00:00 stdout P Second line of the log entry
// 2021-03-31T12:59:28.573159188+00:00 stdout F Last line of the log entry
//
// Here we will emulate CRI-O split by direct writing formatted content
