Add postscript for InfiniBand

[lbgracioso]

This PR is to fix issue #38

Run chdef compute -p postscripts=confignetwork to configure InfiniBand (if using it).

The implementation is not good.

It assumes that a group named compute exists and changes every system configuration that are already on the compute group.

That will not solve the issue and will add inconsistencies to the program.

1. The software is unaware if IB exists or not, and even when it does not exist it will run the chdef command.

2. In this stage of the software the will be nothing on the supposed compute group. So the command is irrelevant.

3. Those modifications should be done in other place, we need to verify if xCAT supports adding that to the osimage instead. That would fix the issue for everything that will be added later.

4. But also changing on the osimage is not trivial: we need to check in advance which images are available and make a decision after.

We have a problem then, because other functions (for example, XCAT::resetNodes and XCAT::setNodesImage) use compute as default. If it doesn't exist, these functions are also broken. How we can fix that?

XCAT::configureInfiniband should verify if it exists or not - and that should be a new issue, not related to this PR.
