Catch runtime exceptions when parsing DHCP packets

Fix merge conflict into nyc-mr1-security-a-release
This patch adds a try catch all to DHCP packet parsing so that
DhcpClient does not choke on malformed packets, brinding down with it
the whole framework.

Test: added new unit tests catching the issue fixed in this patch.
