Install liberasurecode for CentOS

Since I747c2b8754effbc6ec82af3bf7543fd9599a6c14 we do not install
the RDO package repository anymore and thus liberasurecode-devel cannot
be installed.

Add new script tools/test-setup.sh that is called by OpenStack CI jobs
for tox jobs to set up.

The script enables the RDO repository and install the dependencies
liberasurecode-devel and yasm for CentOS 7 and RHEL 7.
