[ovs-dev] [upgrades 4/4] ovs-vsctl: Replicate only tables and columns that are actually needed.

Until now, ovs-vsctl has always fetched a complete replica of the Open
vSwitch database at startup time. This is a little expensive, but that is
not normally a problem because the database is small. However, it can
cause problems when Open vSwitch is partially upgraded: if ovs-vsctl is
upgraded before the database, and new columns or tables were added to the
database schema in the newer version of Open vSwitch, then ovs-vsctl will
report an error and fail to work, because it cannot monitor the new
columns. The same problem occurs if the database is upgraded before
ovs-vsctl and columns or tables were removed in the new version of Open
vSwitch.
This commit fixes the problem in the most common case, by making ovs-vsctl
only replicate the columns and tables in the database that it will actually
use during a given execution. This will still fail if the database has
changed in major ways, but only if the changes would actually cause
problems for what ovs-vsctl is trying to do anyhow.
Bug #3388.
