This enables the firewall/mangle tables rules to ACCEPT instead of RETURN, which
is the same behaviour as observed in ACS 4.5. By accepting the traffic, guest
VMs will be able to communicate tcp traffic between each other over snat public
IPs.

Fix public IPs not being removed from the VR when deprovisionedThis PR replaces #1706. It does not remove the IP from the database, but it does deprovision the IP correctly from the VR when the public IP is removed.

CLOUDSTACK-9757: Fixed issue in traffic from additional public subnetAcquire ip from additional public subnet and configure nat on that ip.
After this pick any from that network and access additional public subnet from this vm. Traffic is supposed to go via additional public subnet interface in the VR.

This change removes an unnecessary conversion from IPNetwork
to list in one of the router scripts. This makes the router
faster at processing static NAT rules, which can prevent
timeouts when attaching or detaching IPs.
The password server in RVRs has wrong parameters as the gateway of guest nics is None.
In this case, we should get the gateway from /var/cache/cloud/cmdline.
-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
In some cases the UDP checksums in packets from DHCP servers are
incorrect. This is a problem for some DHCP clients that ignore
packets with bad checksums. This patch inserts an iptables rule
to ensure DHCP servers always send packets with correct checksums.
Due to this bug DHCP offers are sometimes not accepted by Instances.
The end-result without this fix is no connectivity for the Instance
due to the lack of a IPv4 address.

DNS on VR should not be publically accessible as it may be prone to DNS
amplification/reflection attacks. This fixes the issue by only allowing VR
DNS (port 53) to be accessible from guest network cidr, as per the fix in:
https://issues.apache.org/jira/browse/CLOUDSTACK-6432
- Only allows guest network cidrs to query VR DNS on port 53.
- Includes marvin smoke test that checks the VR DNS accessibility checks from
guest and non-guest network.
- Fixes Marvin sshClient to avoid using ssh agent when password is provided,
previous some environments may have seen 'No existing session' exception without
this fix.
- Adds a new dnspython dependency that is used to perform dns resolutions in the
tests.

Lower the time we wait for interfaces to appearWaiting for interfaces is tricky. They might never appear.. for example when we have entries in `/etc/cloudstack/ips.json` that haven't been plugged yet. Waiting this long makes everything horribly slow (every vm, interface, static route, etc, etc, will hit this wait, for every device). We've seen CloudStack send an `ip_assoc.json` command for `eth1` public nic only and then the router goes crazy waiting for all other interfaces that were there before reboot and aren't there. If only the router would return to the mgt server a success of `eth1`, it would get the command for `eth2` etc etc. Obviously, a destroy works much faster because no state services, so no knowledge of previous devices so no waits :-)
After a stop/start the router has state in `/etc/cloudstack/ips.json` and every commands waits. Eventually hitting the hardcoded 120 sec timeout.

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.

- Use the router to retrieve the instance ID
- Check if the VPC is redundant in order to reuse the private gateway address.
- Brings the private gateways interfaces up.
We need to send an Unsolicited ARP to the gateway, instead of our own address. We now encounter problems when people deploy/destroy/deploy and get the same public ip.
- 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 cidr was replaced by the single IP, which broke the feature.
- Wait during transition from master to backup otherwise the test fails due to wronge state
- We use no preempt mode with state set as EQUAL to both nodes, no need to have Priotities setup
- Do not add IPs as comments to the configuration. If a new guest interface is added, the file will change anyway.
- This was used in the past when keepalived would restart for each new interface added
- Removed the long sleep form the tests: we now sleep 5 seconds per PF rule added
CLOUDSTACK-8616 - Fix keepalived.ts/2 files comparison
- Add call to set_fault() in case of router transits to that state
