[OVN] Spread OVN metadata agent heartbeat response in time
This patch implements [1] and [2] in the OVN agent
``SbGlobalUpdateEvent`` event class.
To avoid mass response of OVN agents on heartbeat update, this patch
postpones the "Chassis_Private" table update for random number of
seconds in maximum range of 10 seconds. The actual value will be the
minimum between (cfg.CONF.agent_down_time // 3) and 10 seconds.

Title:
[OVN] The ``SbGlobalUpdateEvent`` event in the OVN agent should
implement LP#1991817
Status in neutron:
Fix Released
Bug description:
The bug LP#1991817 implemented a method to spread the update of the
OVN Metadata agent heartbeat during a limited period of time. That
limited the synchronization of all agents when updating their own
"Chassis_Private" register and limited the OVN SB usage peaks.
NOTE: above the implementation for LP#1991817 [1], it is also needed
to implement LP#2020215 too.
