[PATCH OSSTEST 05/12] Add and expose some testsupport APIs

[Robert Ho <robert.hu@intel.com>]

When install L2 guest, we will need to invoke
 'select_ether' to get guest MAC address. So here expose select_ether(). And
 also, we added another function 'guest_editconfig_cd' and expose it. This
 function bascically changes guest boot device sequence and alter its
 on_reboot behavior to restart.
