Moved BGP code and Router code into their own bundle.
The main goal of this is to allow routing code to be used by multiple
applications.
Changes include:
* Created an onos-app-routing bundle and moved BGP code and routing code
into it.
* Created an onos-app-routing-api bundle as a common API bundle between
onos-app-routing and onos-app-sdnip, to prevent circular dependencies.
* Moved API classes into onos-app-routing-api bundle.
* Made Router and BgpSessionManager into OSGi components. This is not quite
clean, because there is still a chain of start() method calls from SdnIp
through to BgpSessionManager to preserve startup order. This should be
revisted so components can be started using activate()
* Created BgpService and RoutingService APIs to glue different components
together.
* Many unit test changes. A lot of the previous unit tests spanned the
Router and IntentSynchronizer classes, but this is not possible any more
since these classes are in different bundles. I had to rewrite some of
these tests so that each unit test class only tests one real class. A
nice side-effect is that the tests are now simpler because each test
tests less functionality.
* Removed SdnIp test seeing as it doesn't run automatically, was already
broken and has been largely superseded by other unit tests and the nightly
functional tests.
