Updated StrongSwan VPN ImplementationThis PR is a merge of @jayapalu changes in #872 and the changes I had to make to get the functionality working.
I have done pretty extensive testing of this code so far and we are looking to be in pretty good shape. One thing to note is that a `Diffie-Hellman` group **is required** in order for this feature to work correctly. It is not highlighted in the tests below, but I have shown that the `PFS` is not required for this feature to work. In #872 I have shown a more exhaustive set of tests of this code, but I have limited this set of tests to a recommended `IKE` and `ESP` configuration in order to reduce the noise and test the other areas of functionality.
**Test Results**
I am testing this functionality by creating two VPCs with VMs in each and creating a S2S VPN connection between the two VPCs. Then I SSH into a VM in one VPC and I ping the private IP of a VM in the other VPC. Then I tear it down and try a different configuration.
_Setup_
```
VPC 1 VPC 2
===== =====
VPN Gateway VPN Gateway
VPN Customer Gateway VPN Customer Gateway
VPN Connection <---> VPN Connection
- Passive = True - Passive = False
```
_Legend_
`SKIP` => At least one of the VPN Connections did not come up, so no test was run.
`OK` => The ping test was successful over the S2S VPN connection.
`FAIL` => The ping test failed over the S2S VPN connection.
`Passive` => Specifies if either the `<vpc_1> : <vpc_2>` sides of the VPN Connection is set to passive.
`Conn State` => Specifies the connection status of the `<vpc_1> : <vpc_2>` VPN Connection in the UI.
`Requires Reset` => If the ping test does not result in an `OK`, then a VPN Connection Reset is performed on either `<vpc_1> : <vpc_2>` sides of the VPN Connection based on which side is not showing `Connected`. The results in the `Status` column is the final result after the reset is performed.

complete implementation of the StrongSwan VPN feature
Signed-off-by: Rajani Karuturi <rajani.karuturi@accelerite.com>
-when processing static nat rule, add a mangle table rule, to mark the traffic
from the guest vm when it has associated static nat rule so that traffic gets
routed using the route tabe of the device which has public ip associated
-fix the case where nic_device_id is empty when ip is getting disassociated
resulting in empty deviceid in ips.json
-add utility methods in CsRule, and CsRoute to add 'ip rule' and 'ip route' rules respectivley
-ensure traffic from all public interfaces are connection marked with device number, and restored
for the reverse traffic. use the connection marked number to do device specific routing table lookup
fill the device specific routing table with default route
-component tests for testing multiple public interfaces of VR
CLOUDSTACK-9480: Egress Firewall: Incorrect use of Allow/Deny for ICMP
fix ensures, ICMP, TCP, UDP are handled similalry w.r.t egress rule action
CLOUDSTACK-9495: Egress rules functionalty broken when protocol=all specified
when protocol=all specified, CIDR was ignored. Fix ensures if CIDR is specified
its always used in configuring iptable rules
2 new test cased to test /32 CIDR
- Ensure that FW_EGRESS_RULE chain exists after upgrading the router
- Flush allow all egress rule on 0.0.0.0/0, if such a rule exists in the config
it will be added later (CLOUDSTACK-9437)

Seems to have a license issue so reverting for now.
This reverts commit 9a20ab8bcbbd39aa012a0ec5a65e66bcc737ee0e, reversing
changes made to 7a0b37a29a8be14011427dcf61bf3ea86e47dbf4.
Restore iptables at once using iptables-restore instead of calling iptables numerous timesThis makes handling the firewall rules about 50-60 times faster because it is generated in memory and then loaded once. It's work by @borisroman see PR #1400. Reopened it here because I think this is a great improvement.
* pr/1482:
Resolve conflict as forceencap is already in master
Split the cidr lists so we won't hit the iptables-resture limits
Check the existence of 'forceencap' parameter before use
Do not load previous firewall rules as we replace everyhing anyway
Wait for dnsmasq to finish restart
Remove duplicate spaces, and thus duplicate rules.
Restore iptables at once using iptables-restore instead of calling iptables numerous times
Add iptables copnversion script.

Apply static routes on change to master stateRefactored static routes for private gateways so they also get loaded when the router switches to master state. Otherwise they're lost and connections drop after fail over.

Tested it on 4.7 single Xen server zone:
command:
```

- Stop KeepaliveD/ConntrackD if the eth2 (guest) interface is not configured and UP
- Only setup the redundancy after all the router configuration is done
- Open the FW for the VRRP communitation
- 224.0.0.18 and 225.0.0.50
- Set keepalived.conf.templ by default to use interface eth2 (guest)
- It will be reconfigured anyway, but having eth2 there is more clear
- The default is Accept and will be changed based on the configuration of the offering.
CLOUDSTACK-8934 - The default egress is set as Deny in the router.
- We had to change it on the Java side in order to make the apply it once the default is defined as allowed on the net offering
CLOUDSTACK-8881: Fixed Static and PF configuration issue1. For static nat filter rules are not configured in VR.
