Add virsh domif-setlink domif-getlink test

Introduce virsh domif-setlink domif-getlink  testing:

    1. Positive testing
        1.1 Running domain and shutting off domain testing
        1.2 Setlink domain interface up and down then check
        1.3 Options "--config" testing
        1.4 Interface name and MAC address testing

    2. Negative testing
        2.1 Invalid options testing
        2.2 Shutting off domain with interface name

virt.ks: Add qemu-guest-agent package in RHEL6's kickstart file

qemu-guest-agent package exists in the cd image after RHEL6.3,
thus install it directly in guest installation stage.

For those RHEL6 guest before RHEL6.3, add a "ignoremissing"
option to let them ignore this new package.

shared.unattended: Use fixed partition for RHEL5/6 guests

Currently we use autopart in all rhel guests, which bring
trouble when RHEL5 RHEL6 guests w/ huge(64+G) RAM. The
swap partition will be really huge and not enough space
for the root partition, thus installation fails.
(we met this problem on huge RAM host before).

With this patch, the RHEL5 RHEL6 guest will have only 2
physical partitions(/boot, PV), and the PV contains 2
 LVs(/, swap).

|     | /    |swap|
|/boot|----LVM----|
|     |    PV     |
|---------------- |
|guest hard drive |

Note:
1) we can use plain partitions here (w/o LVM) to gain the
   possible tiny performance improvement, but I prefer to
   choose the LVM scheme, a little bit complex partioning
   scheme but test more (also testing the lvm layer).
2) RHEL3, RHEL4, RHEL7 kickstart config didn't update here,
   because:
   The default kernel shipped w/ RHEL3, RHEL4 dont support
   such huge RAM, so they will not met this issue.
   The anaconda of RHEL7 looks fixed this problem, install
   w/ autopart will not create a huge swap partition.
