This PR fixes#5058
when start a vm, the old entries in databag for the vm (with same mac addresses) should be removed then set again, to avoid duplicated records in dhcpentry databag and also /etc/dhcphosts.txt
Testing with Isolated networks:
(1) stop vm, change vm ip address, start vm
vm info is updated in /etc/dhcphosts.txt and /etc/cloudstack/dhcpentry.json
(2) stop vm, expunge vm.
vm is removed from /etc/dhcphosts.txt and /var/lib/misc/dnsmasq.leases
Testing with VPC:
(1) create vm in 2 vpc tiers
vm has 2 entries in /etc/dhcphosts.txt, and /etc/cloudstack/dhcpentry.json
(2) stop vm, change ip addresses, change nics order, start vm
entries are updated in /etc/dhcphosts.txt and /etc/cloudstack/dhcpentry.json
(3) remove a nic from vm (hot unplug)
vm nic is removed from /etc/dhcphosts.txt and /var/lib/misc/dnsmasq.leases
entry in /etc/cloudstack/dhcpentry.json is updated.
IKE version allows selecting ike (autoselect), ikev1, or ikev2.
Split connections gives an option of separating the first right subnet from the rest, and kicking out individual statements for each right subnet for better cross-compatibility.

There is a potential security issue with having http access to the VR from anywhere.
This PR restricts http access to the VR to the internal network only.
This contains 3 main changes
(1) add NETWORK_STATS_ethX for all nics with public ips in VPC VRs (current: NETWORK_STATS_eth1)
(2) DO NOT create records in user_statistics for each VPC tier (only one record per public nic per VPC VR)
(3) send NetworkUsageCommand before unplugging a NIC with public IPs from VPC VR
Steps to reproduce the issue
(1) create two vm wei-001 and wei-002, start them
(2) check /etc/cloudstack/dhcpentry.json and /etc/dhcphosts.txt in VR
They have entries for both of wei-001 and wei-002
(3) stop wei-002, and restart VR (or restart network with cleanup).
check /etc/cloudstack/dhcpentry.json and /etc/dhcphosts.txt in VR
They have entries for wei-001 only (as wei-002 is stopped)
(4) expunge wei-002. when it is done,
check /etc/cloudstack/dhcpentry.json and /etc/dhcphosts.txt in VR
They do not have entries for wei-001.
VR health check fails at dhcp_check.py and dns_check.py

* vpc: fix ips on wrong interfaces after rebooting vpc vrs

The DNS entry "data-server" was not added in /etc/hosts.
Since the VR is now considered as a "dhcpsrvr" (?), we need to apply this commit to add this DNS entry.
/etc/hosts is fully rewritten by this script.

As discussed in #3937 (comment)
a rule for port forwarding in VPC router might not be needed.
This fixes the failed result of health check for network VRs.
When Guest VM add secondary nic, will get wrong hostname "infiniteh" from dhcp server
infiniteh -->infinite
cat /etc/dhcphosts.txt
02:00:0b:ef:00:04,set:192_168_4_18,192.168.4.18,gumd-tes3,infiniteh
The previous setup of many hours would not work, due to some internal dnsmasq issues - lease was set correclty, but dnsmasq was setting the dhcp-renew-time (and rebind time) to less than 2 years from the date the lease was issued.
Using "infinite" as the value (instead of the number) works as expected - and (atm) the renew date is set to year 2088, etc.

since 4.11.3, haproxy is always restarted when add/delete a lb rule.
When haproxy is started, the processes are
```
root@r-854-VM:~# ps aux |grep haproxy
root 22272 0.0 0.2 4036 668 ? Ss 07:52 0:00 /usr/sbin/haproxy-systemd-wrapper -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid
haproxy 22274 0.0 2.3 38444 5856 ? S 07:52 0:00 /usr/sbin/haproxy-master
haproxy 22275 0.0 0.3 38444 880 ? Ss 07:52 0:00 /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid -Ds
```
When haproxy is reload, the processes are
```
root@r-854-VM:~# ps aux |grep haproxy
root 22272 0.0 0.2 4168 632 ? Ss 07:52 0:00 /usr/sbin/haproxy-systemd-wrapper -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid
haproxy 22283 0.0 2.3 38444 5884 ? S 07:53 0:00 /usr/sbin/haproxy-master
haproxy 22286 0.0 0.3 38444 880 ? Ss 07:53 0:00 /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid -Ds -sf 22275
```
We need to change the pid file from /var/run/haproxy.pid to /run/haproxy.pid, so the haproxy will be reloaded instead of restarted.
When we create a vm in the network with redundant VRs, the lease file in the vm (for example /var/lib/dhcp/dhclient.eth0.leases) shows the dhcp-server-identifier is the guest ip (not vip/gateway) of master VR. That's the ip ipaddress where the vm fetch password and metadata from.
if we stop the master VR (then backup will be master) or restart the network with cleanup (VRs will be created), the guest ip of master VR changes so vm are not able to get metadata/ssh-key using the ips in dhcp lease file.
Setting up metadata/password/dhcp server on gateway instead of guest IP in redundant VRs will fix the issues.
