[toranj] test case for adding IPv6 addresses with same prefix on multiple nodes (#2915)
This commit adds a new test script for `toranj` test frame-work covering the situation when IPv6 addresses with same prefix are added/removed on multiple nodes. The test verifies that the on-mesh prefix list on all nodes stays consistent and updated as the addresses are added/removed and nodes are reset.
