eliminate `component%component_type` or reduce it to the minimal amount of information necessary

[Juergen Reuter]

This is issue #4 from gitlab.

Could be steered via component%config%nlo%get_nlo_type () .

JRR looked into this: Looked a little bit into the code. Indeed, this is only marginally used. COMP_RESUM is never used. COMP_SUB, COMP_PDF, COMP_MISMATCH and COMP_VIRT are set, but never used. COMP_REAL is used only to deactive the real component (which is probably right now when use_real_finite is set to true), COMP_MASTER is only used for a tricky hocuspocus for combined integrations, and COMP_REAL_SING and COMP_REAL_FIN are actually used. The first one only for debug output, and to specify the is_subtraction flag. The only one that seems to be really used properly is COMP_REAL_FIN. So this can/should be simplified, maybe even eliminated.

WK's suggestion: Move the information into the process_component_manager(_nlo).
