Change in policy rule does not effect traffic on active flows.
Steps to reproduce:-
1. create a VN "vn-1"
2. create a Policy with rule:-
source vn - vn-1
dest-vn - vn-1
protocol - ICMP
action - deny
3. create 2 VM's "vm-11" and "vm-12" in "vn-1"
4. start ping to vm-12 from vm-11
5. packets should get dropped.
6. a drop flow should get created which show action as - Dropped by Policy - D(Policy)
7. agent introspect page should show the policy action for ICMP as drop
8. change the rule action to "PASS" from "DENY"
9. agent introspect page shows the policy action for ICMP as "pass"
10. but packets are still not allowed and the flow shows as dropped. - Dropped by Policy - D(Policy)
