replace GRAM workflow tests with bosco

Condor support for GRAM is broken. In addition GRAM is no longer officially supported . As part of this we will move our bamboo tests to a bosco setup to test for remote submissions. as part of this we have setup a dockerized slurm cluster on corbusier

here is a site catalog entry for site CCG to be used for tests.
