pyroute2.IPDB is an interesting entity. It's much more than a simple interface to `ip` command, as it is more similar to a database process. When created IPDB object spawns a thread that will be responsible for updating the object with changes to the underlying OS. Thread stays up until the user will call `release()` method. Turns out code in kuryr_kubernetes.cni.binding wasn't taking that into account and was slowly leaking threads (and possibly processes). This became apparent when running Kuryr with CNI daemon enabled. This commit fixes the problem by switching all IPDB usages to context managers, so `release()` method is called automatically. Also the IPDB objects cache is removed as already released IPDB objects cannot be reused. kuryr_kubernetes.cni.binding modules were missing unit tests, this commit adds them as well.
