[ovs-dev] [PATCH 1/4] ovs-vsctl: Create AutoAttach records on demand, for backward compatibility.

The AutoAttach table is new in OVS 2.3.90, but ovs-vsctl was creating a
record in the table unconditionally whenever it created a new bridge.
This caused a gratuitous incompatibility with older databases, which can
be a problem during upgrade. This commit switches to creating the
AutoAttaach record for a bridge lazily, only when the first mapping is
created for the bridge.
