Creditfacade field is not set in creditmanager when cm is initialized.

[harsh-98]

Previously, when creditconfigurator was deployed it use to set creditfacade in cm and emit setCreditFacade event. Now that functionality is removed. Kindly, set creditfacade field in cm and add setCreditfacade back in creditconfigurator. (setCreditfacade event emission is not necessary as i can get that via call, but u have to set creditfacade)

New flow:
deployCreditManager is called in marketconfigurator, this creates cf,cc,cm. cc doesn't set cf in cm.
