Observation:
The iptables SNAT rules added from hostcfgd during system bootup, cleaned up by some module.

Root cause:
NAT mgr clears the iptables NAT rules added by hostcfgd during bootup.

Potential solution:
Clear the NAT rules added only by natmgr not all rules in kernel.

NAT feature pull request:
#1059

…on failures (sonic-net#1292)

To fix the issue sonic-net/sonic-buildimage#5972
warm-reboot with force flag ignores ASIC config checksum mismatch along with orchagent RESTARTCHECK failure.
This commit accounts for a use case when checksum-verification should be ignored but orchagent pause check should not be ignored.
The change is to add a new option in fast-reboot script to ignore ASIC checksum verification failures.
