Fix condition loading in Castor DQM online client

[diguida]

The Castor DQM online client in DQM/Integration/python/clients/castor_dqm_sourceclient-live_cfg.py should load all the conditions from the online GT provided by DQM configuration, and eventually customise them, not just define the Castor records on their own.

This commit reverts 099ad01 which is a regression, as it reintroduces the bug fixed when testing in the online playback by commit 6943411#diff-3d9d457e24541d87ac089a37cc36fd1f
