tempest.conf.sample is not in etc now.

[Shuquan Huang]

We're using oslo-config-generator to generate a config file other than copy the sample. We should update the description in qucikstart of README.rst.

The easiest way to create a configuration file is to copy the sample one in the etc/ directory

$> cd $TEMPEST_ROOT_DIR
$> cp etc/tempest.conf.sample etc/tempest.conf
After that, open up the etc/tempest.conf file and edit the configuration variables to match valid data in your environment. This includes your Keystone endpoint, a valid user and credentials, and reference data to be used in testing.
