Subject: [PATCH] vswitchd: Add OVS version to database, give system info its
own columns.
Until now, nothing in the database has reported the Open vSwitch version
number. This commit adds that.
In addition, this commits moves the system type and version from
external-ids to individual columns, because we decided that these were
important enough not to relegate them to a grab-bag field.
