This series fixes 2 issue in rtla timerlat and osnoise parsing.
1. Make -C/--cgroup option more user-friendly. Currently rtla timerlat
and osnoise parses does not allow to specify tracer's threads cgroup
name as `-C [cgroup]` or `--cgroup [cgroup]`. Second patch fixes this
by allowing users to specify cgroup in the aforementioned manner.
2. When specifying `-t/--trace` before `-a/--auto`, trace filename is
override to default <osnoise|timerlat>_trace.txt. For example, when
running rtla as
`rtla timerlat top -t custom_file.txt -a 100`
when the threshold is reached, timerlat_trace.txt file is created
instead of specified custom_file.txt. Third patch addresses this
issue.
