G0 interpolation Kubo-Martin-Schwinger boundary condition check

[PDoakORNL]

With the update of the interpolation of G0 in TpEqualTimeAccumulator, I went looking for similar code segments.

We have the following places in the code where we might should consider the KMS boundary conditions of the fermionic thermal Greens function. If @gbalduzz is correct in #127 which I think he is the following need to be examined.

• include/dca/phys/dca_step/cluster_solver/ctaux/walker/tools/g0_interpolatio/g0_interpolation_cpu.inc
• include/dca/phys/dca_step/cluster_solver/ss_ct_hyb/walker_tool/ss_hybridization_walker_routines.hpp
• src/phys/dca_step/cluster_solver/ctaux/walker/tools/g0_interpolation/g0_interpolation_kernels.cu
• include/dca/phys/dca_step/cluster_solver/shared_tools/accumulation/sp/sp_accumulator.hpp
• include/dca/phys/dca_step/cluster_solver/ss_ct_hyb/accumulator/sp/sp_accumulator_nfft.hpp

also the solvers should be updated to use the same interpolation object.
