tools/rv: Correct the grammatical errors in the comments
The word "trace" begins with a consonant sound, so "a" should be used instead of "an".

tools/rv: Add in-kernel monitor interface
Add the ability to control and trace in-kernel monitors. This is a generic interface, it will check for existing monitors and enable standard setup, like enabling reactors.
For example:
# rv list wip wakeup in preemptive per-cpu testing monitor. [OFF] wwnr wakeup while not running per-task testing model. [OFF]
# rv mon wwnr --help rv version 6.1.0-rc4: help
usage: rv mon wwnr [-h] [-q] [-r reactor] [-s] [-v] -h/--help: print this menu and the reactor list -r/--reactor 'reactor': enables the 'reactor' -s/--self: when tracing (-t), also trace rv command -t/--trace: trace monitor's event -v/--verbose: print debug messages
available reactors: nop printk panic
# rv mon wwnr --trace <TASK>-PID [CPU] TYPE ID STATE x EVENT -> NEXT_STATE FINAL | | | | | | | | | rv-3613 [001] event 3613 running x switch_out -> not_running Y sshd-1248 [005] event 1248 running x switch_out -> not_running Y <idle>-0 [005] event 71 not_running x wakeup -> not_running Y <idle>-0 [005] event 71 not_running x switch_in -> running N kcompactd0-71 [005] event 71 running x switch_out -> not_running Y <idle>-0 [000] event 860 not_running x wakeup -> not_running Y <idle>-0 [000] event 860 not_running x switch_in -> running N systemd-oomd-860 [000] event 860 running x switch_out -> not_running Y <idle>-0 [000] event 860 not_running x wakeup -> not_running Y <idle>-0 [000] event 860 not_running x switch_in -> running N systemd-oomd-860 [000] event 860 running x switch_out -> not_running Y <idle>-0 [005] event 71 not_running x wakeup -> not_running Y <idle>-0 [005] event 71 not_running x switch_in -> running N kcompactd0-71 [005] event 71 running x switch_out -> not_running Y <idle>-0 [000] event 860 not_running x wakeup -> not_running Y <idle>-0 [000] event 860 not_running x switch_in -> running N systemd-oomd-860 [000] event 860 running x switch_out -> not_running Y <idle>-0 [001] event 3613 not_running x wakeup -> not_running Y
