Add a test for the perf daemon 'signal' command. The test sends a signal
to configured sessions and verifies the perf data files were generated
accordingly.
Committer testing:
[root@five ~]# perf test daemon
76: daemon operations : Ok
[root@five ~]# perf test -v daemon
76: daemon operations :
--- start ---
test child forked, pid 790017
test daemon list
test daemon reconfig
test daemon stop
test daemon signal
signal 12 sent to session 'test [790268]'
signal 12 sent to session 'test [790268]'
test child finished with 0
---- end ----
daemon operations: Ok
