Subject: [ovs-dev] [PATCH ovn v3] utilities: increase OVSDB inactivity probe
interval for ovn-*ctl

For large OVN_Southbound (or other) databases the default interval of 5000 ms
could be not sufficient to run. This patch adds configuration of OVSDB
inactivity probes for ovn-*ctl utilities.
Initially, on the utility start the hardcoded value of 120000 ms is set.
For daemon-mode it is possible to configure intervals in OVN Northbound and
OVN Southbound databases for ovn-nbctl and ovn-sbctl utilities respectively.
Use
OVN_Northbound.NB_Global.options.nbctl_probe_interval for ovn-nbctl and
OVN_Southbound.SB_Global.options.sbctl_probe_interval for ovn-sbctl
utilities.
If no DB configuration option was provided, the initial (120000 ms) interval
is left.

v2 -> v3:
- Addressed Dumitru's and Mark's suggestion to split ovn-{n,s}bctl
configuration option dbctl_probe_interval for nbctl_... and sbctl_... .
- Added NEWS entry.
- Fixes typos.
- Added ovn-sb man entry for new option.
- Moved constant from ovn-util.h to ovn-dbctl.h.
