tests: add simple bond tests for both nm and initscripts
* add a helper to create two veth devices with IPv4/IPv6 infra * add a bond in active-backup mode with miimon value * add two slaves connections for two veth devices * check automated IPv4/IPv6 addresses are assigned to master * check all connections are present * add a helper to delete previously created veth device setup
