LGTM 👍
I have tested ros2 caret record command in iron environment.
when specifing --subbuffer-size-{ust,kernel} option:
ros2 caret record --subbuffer-size-ust 65536 --subbuffer-size-kernel 65536
UST tracing enabled (1 events)
kernel tracing disabled
context (3 fields)
writing tracing session to: /root/.ros/tracing/session-20230901023936
press enter to start...
subbuffer ust = 65536
subbuffer kernel = 65536
press enter to stop...
stopping & destroying tracing session
without any option:
# ros2 caret record
UST tracing enabled (1 events)
kernel tracing disabled
context (3 fields)
writing tracing session to: /root/.ros/tracing/session-20230901023906
press enter to start...
subbuffer ust = 32768
subbuffer kernel = 131072
press enter to stop...
stopping & destroying tracing session

Description
In caret, the lttng buffer size was hard-coded in the forked ros2_tracing.
This was done to prevent trace data from being lost.
In ros2_tracing since iron, it is possible to change the buffer size of lttng externally.
This PR provides an option to specify the buffer size from the ros2caret cli.
