Huge tests should have a summary page in the end

[Po-Hsu Lin]

For example, the stress smoke test will print the summary in the end, which will be useful for review.
As we can check this summary for:
  * If the test has finished properly, or get killed by the timeout
  * If there is any new failures

 Summary:
   Stressors run: 175
   Skipped: 2, bind-mount watchdog
   Failed: 0,
   Oopsed: 0,
   Oomed: 0,
   Passed: 173, access af-alg affinity aio aiol bad-altstack bigheap branch brk cache cap chdir chmod chown chroot clock clone context cpu crypt cyclic daemon dccp dentry dev dev-shm dir dirdeep dnotify dup dynlib enosys epoll eventfd fallocate fanotify fault fcntl fiemap fifo file-ioctl filename flock fork fp-error fstat full funccall futex get getdent getrandom handle hdd hrtimers icache icmp-flood inode-flags inotify io iomix ioport ioprio itimer key kill klog lease link locka lockbus lockf lockofd madvise malloc mcontend membarrier memfd memrate memthrash mergesort mincore mknod mlock mmap mmapaddr mmapfixed mmapfork mmapmany mq mremap msg msync netdev netlink-proc nice null open personality physpage pipe pkey poll prctl procfs pthread ptrace pty radixsort rawdev readahead rename revio rlimit rmap rtc schedpolicy sctp seal seccomp seek sem sem-sysv sendfile set shm shm-sysv sigfd sigfpe sigio sigpending sigpipe sigq sigrt sigsegv sigsuspend sleep sock sockdiag softlockup splice stackmmap stream swap switch symlink sync-file sysbadaddr sysinfo sysfs tee timer timerfd tlb-shootdown tmpfs tree tsearch udp udp-flood unshare urandom userfaultfd utime vfork vm vm-addr vm-rw vm-segv vm-splice wait yield zero zombie

Known tests that need this summary:
  * kvm-unit-tests
  * ubuntu_ltp_syscalls

[Po-Hsu Lin (cypressyew)]

Now we have ubuntu_ltp_syscalls printing summary:
https://kernel.ubuntu.com/git/ubuntu/autotest-client-tests.git/commit/?id=0aa562bd0cdc80e1427a67cb13cf8a6f76fd47d1

kvm-unit-test split into small tests:
https://kernel.ubuntu.com/git/ubuntu/autotest-client-tests.git/commit/?id=4c99b09870f2e357a741fad31c0c3867fefcb0a6

And ubuntu_ltp into small groups (with summary printed):
https://kernel.ubuntu.com/git/ubuntu/autotest-client-tests.git/commit/?id=d06a255d74e62a9a18586d9d9a94b9fc1da9ec1d

I will call this done.

If we ever need to add this feature for another test, a new bug report should be reported.
Thanks
