* Define exceptions BayModelNotFound and BayModelAlreadyExists. These two exceptions were used in the code but not defined. * Remove methods reserve_baymodel and release_baymodel, since it does not make sense to reserve/release a baymodel. * Remove exception BayModelAssociated. This exception was used without being defined and does not make sense for baymodel. * Remove unrelated code at method create_baymodel. Change-Id: I6946d771d40c5274f59b94d17542d84685c26e27
