Topotato: Assert Ping

[eznix86]

Untested yet, but waiting for a review on implementation.

implementation:

~yield from AssertPing.make(r1, iface, r2)~

yield from AssertPing.make(r1, "r1-s1", "192.168.1.2") 
yield from AssertPing.make(r1, "r1-s1",  str(r2.iface_to("s1").ip4[0].ip))

Updated the code, it seems like I do not receive the expected packet with IP/ICMP (tried with ScapySend + AssertPacket Combination) and remained the same results:

E       topotato.exceptions.TopotatoPacketFail: did not receive a matching packet for:
E               def expect_pkt(ip: IP, icmp: ICMP):
E                   return True
