Added global config to enable/disable rp_filter for domR.
previous commit: d966906374d4a0cb8fa57326a1f7625c871f64fd
Test Case-1 :
1) Set network.disable.rpfilter global config to true
2) Restart the domR
3) check the settings reflected in proc filesystem
- for public interface like eth2,eth3 : /proc/sys/net/ipv4/conf/eth2/rp_filter should have 0 , and rest other interfaces should have value of 1
Test Case-2 :
1) set network.disable.rpfilter global config to false
2) Restart the domR
3) check the settings reflected in proc filesystem
- for public interface like eth2,eth3 : /proc/sys/net/ipv4/conf/eth2/rp_filter should have 1 , and rest other interfaces should also have value of 1
The reason is:
1. In redundant router, we won't enable eth2(public network interface) until
keepalived determine the router is MASTER.
2. ipassoc.sh normally kick in before keepalived process running. And it would
set eth2's IP address using "ip addr add $dev $ip"
3. "ip addr add $dev $ip" won't add mask for the device, then there is no way to
update broadcast address for eth2. Then broadcast address is 0.0.0.0.
4. As long as "ip addr add $dev $ip" executed, later executed "ifconfig $dev $ip
netmask $mask" won't calculated the broadcast address from $ip and $mask.
To fix this, we enable and configure eth2 temporaily when cloud-early-config
executed, then disable eth2 interface. By this way, broadcast address of should
be calculated and set correctly.
status 11083: resolved fixed

commit e4fe14a9ce19fbbdb15bbfaad586d80031ca9fbc break redundant router, because
at time of ping, the network is not up for redundant router.
Add timout for ping
The issue happened quite rare, but indeed can show.
And when the issue happen, the status of redundant router would be "Status:
FAULT".
It's due to ipassoc.sh wasn't executed before the system bring eth2 up and go to
master mode, then eth2 wasn't configured correctly. Then "ip route add default
xx" can't complete.
This commit should fixes the issue.

in the master branch.
Sometime when keepalived start up(during system boot up period), it would fail
to(likely due to unable to receive the packet), and think itself is the only
router, then make itself master.
Add 10 seconds delay after start up to work around the issue.
