Rally verification to use existing tempest

By default, Rally verification requires to do
following things:

* git clone tempest source from upstream
* setup virtualenv for this tempest
* setup testr environment with virtualenv above
* create tempest.conf for this tempest

If tempest is already installed/configured in rootfs
then force Rally to use this existing tempest.

A new introduced option "existing_tempest_config" in /etc/rally/rally.conf
can be used to configure Rally to either use the existing
tempest or to download from upstream.

If the option "existing_tempest_config" is not set then follows
the default path.  If existing_tempest_config is set to absolute
path of tempest config folder (which contains tempest "tools"
and .testr.conf) then Rally uses this existing tempest.
