Re-generating tempest.conf file before starting tests

"rally verify genconfig" command doesn't generate tempest.conf
file if it already exists in the used deployment. This can cause
troubles if some resources (images, flavors etc.) change between
consecutive runs of tempest. The change ensures that tempest.conf
is deleted before executing "rally verify genconfig".
