Yardstick virtualenv support

JIRA: YARDSTICK-620

Currently we recommend using docker to run yardstick.
And it is hard to use virtualenv to install yardstick.
So I modify install.sh in yardstick root path.
It will support using virtualenv to install yardstick(including API) in
linux.
In this patch, I make yardstick support read yardstick configuration
have priority over constants.
