Umd 3 htcondor

Here is first version of the templates for configuring Cream-ce with htcondor batch system. A number of features is still missing (e.g. possibility to run cream and htcondor master on 2 different machines).

Are you sure this is correct? I guess it should be true... (see https://github.com/quattor/template-library-grid/pull/117). More fondamentaly, why not to use the standard APEL configuration. #117 should be merge first in this case.
