Fix default value for MTUs, when not provided
When networks are created using REST APIs, if the MTU isn't specified
in the request, then a default value of 0 is used. Some use cases, such
as the auto-allocated-topology workflow, call the plugin directly to
create networks, bypassing the layer that inserts this default value.
Commit 68625686a40b3eb75502c8116f23d2297e288ca1 introduced a different
default value at the DB layer, defined by a constant in neutron-lib.
If the maximum MTU size has been configured lower than this constant,
then the user receives an exception, even though they didn't provide
a value for MTU.
This patch changes the default value used in the DB layer, so that
it's consistent with the workflow seen via REST APIs.
