[ovs-dev] [PATCH v3 0/9] tests: Clean up syslog.

[Ilya Maximets]

Each run of the testsuite produces millions lines in a system
log. This is completely unnecessary and makes it difficult to
use system logs on test / build servers.

This series is aimed to disable most of the syslog messages.
There are still few logs that requires significant changes in
tests or code to disable. They will be removed separately if
needed.

Some testing results:
  OS : RHEL 7.5
  CPU: Xeon E5 v4 2.6GHz
  Cmd: make check TESTSUITEFLAGS='-j20'

  Without patches:
      * 3.350.097 Lines of logs in journalctl
      * Execution time: 11 minutes
      * journald eats 100% of one cpu core.

  With patch-set applied:
      * 226 Lines of logs in journalctl
      * Execution time: 2.5 minutes

So, in addition to clean logs, this patch-set significantly
speeds up the testsuite execution in parralel builds (more
than 4 times! in my case).

Side effects:
  * default timeout applied to control utils in a subshell.
  * tests refactored to be more readable.
  * testsuite execution speed up.


Version 3:
  * Replaced bash extention '==' with '=' in patch #2. [Timothy]
  * Rebased on current master.
  * Added ACK from Aaron to all patches except #2, which was
    a bit modified.

Version 2:
  * Fixed accidentially missed '--timeout' in patches 1 and 2. [Aaron]
