and overlay networks, both initially and after a restart.

Currently integration test is a bit flaky because of
variability in the dnet bootup time. Fixed it to wait for
dnet to come up before performing any tests.

Added restart test for default network so that we can test
bridge network persistence. Also added changes to dnet to
delete the default network if it is present.

Currently when docker exits ungracefully it may leave
dangling sandboxes which may hold onto precious network
resources. Added checkpoint state for sandboxes which
on boot up will be used to clean up the sandboxes and
network resources.
On bootup the remaining dangling state in the checkpoint
are read and cleaned up before accepting any new
network allocation requests.
