This parameter sets inactive probe interval of the JSON
session from ovn-metadata to the OVN SB database.
By default this it is 5s which not be sufficient in
loaded systems or during high control-plane activity spikes,
leading to unnecessary reconnections to OVSDB server.
Now it is extended by default to 1 min and it
is configurable.
