conntrackd: add -t option to shorten conntrack timeouts
This patch adds the new option `-t' for conntrackd. This option shortens
the value of the timeout for the cached entries that lives in the
kernel. This option is particularly useful to remove the zombie
established entries that remain in kernel if the user tests the platform
by forcing the takeover from one to another node several times.
We currently use the value of CommitTimeout which is sane for it. Adding
a new option does not seem to add more flexibility IMO.
Once we get the patches to notify user changes via ctnetlink and the
netlink flag NLM_F_ECHO works, we may directly invoke a massive purge of
the entries, however, such solution would still need evaluation.
