  Log Message:
  ovs-ctl: Allow recording hostname separately.

ovs-ctl determines the system FQDN or hostname and records it in
the `external-ids:hostname` field of the `Open-vSwitch` table on
system startup if it is not already set.

This value may be consumed by downstream software and having it
unset or set to a incorrect value could lead to erratic behavior
of a system.

When a system is configured to use an Open vSwitch controlled
datapath as its only network connection, the current ordering of
events would always record a unreliable hostname.

To tackle this problem this patch adds an optional argument that
allows starting Open vSwitch without recording the hostname in
the database as well as a new ctl command to record the hostname
separately. This command can be called by the system startup
scripts when the system is ready to collect and record this
