virttest.qemu_vm: Remove init_pci_addr from VM.

Now vm.init_pci_addr is effected by previous vm.

We set init_pci_addr to 3 in multi_disk.max_disk, but this case still
fail for:
VMPCIOutOfRangeError: Too many PCI devices added on vm 'virt-tests-vm1',
 max supported '31'

because previous case use default value 4.

As init_pci_addr only used in get_free_pci_addr, so remove it from vm
 and only get init_pci_addr in get_free_pci_addr().
Also set default for init_pci_addr to 3.

qemu.control.kernel-version: Bug fix for control.kernel-version

This patch fix three problems in control.kernel-version:
  - Fix the wrong variable name.
  - Remove the parse_file inside control file for host-kernel.cfg
    Just in clude it as other cfg files in your tests-example.cfg
    which is more flexible. And this also can work with the situation
    that without host-kernel.cfg.
  - Don't get the package version if there is no need for package
    version check.

Also add some docstring for how to use the package filter.

KVM Test: Add qmp_command test.

This script have coverd following qmp command:
query-hpet, query-kvm, query-mice, query-status
query-name, query-uuid, query-version, query-chardev
query-blockstats, memsave, pmemsave, query-cpus
cpu, query-vnc, query-block, query-commands
query-balloon, balloon, cont, stop
and a negative test with wrong command.

This script will check result by following way:
cmd_result_check = equal, will compare cmd_return_value with qmp command output.
cmd_result_check = contain, will try to find cmd_return_value in qmp command output.
cmd_result_check = m_equal_q, will compare key value in monitor command output and qmp command output.
cmd_result_check = m_in_q, will try to find monitor command output's key value in qmp command output.
cmd_result_check = post_contain, will try to find cmd_return_value in post command output.

This update is base on upstream QMP patchset.

virttest.asset: Pass on restore_image value

With the work made on the asset library, we forgot to
pass the force param to asset.download_file(), as a
result the test runner --restore-image flag stopped
working.

So fix the problem by passing the appropriate option
to that function.
