Add ACCESS_NETWORK_STATE to Tethering CTS because tests call to
EthernetManager#isAvailable() which is enforcing permission check
now. Without ACCESS_NETWORK_STATE, some tests will fail by lack
of permission.

Ignore-AOSP-First: Security vulnerability issue should not fix on
aosp branch.
This test uses EthernetManager's ability to use test network
interfaces to test tethering. This provides a fairly realistic
integration test for Tethering and its callbacks, IpServer and
DhcpServer, and so on.
It is in a new integration/ directory under Tethering because I
didn't really know where to put it. It's fast enough to run in
presubmit, but it didn't seem to be appropriate to call it a
unit test, and in the future we could also use this test to do
some limited testing of real Ethernet tethering as well.
