Ready for review. Three tests still fail, but I cant figure out why.

src/plugins/analysis/software_components/test/test_plugin_software_components.py::TestAnalysisPluginsSoftwareComponents::test_process_object
src/test/unit/analysis/test_yara_plugin_base.py::TestAnalysisYaraBasePlugin::test_process_object
src/test/unit/analysis/test_yara_plugin_base.py::TestAnalysisYaraBasePlugin::test_process_object_nothing_found

src/plugins/analysis/software_components/test/test_plugin_software_components.py::TestAnalysisPluginsSoftwareComponents::test_process_object

in src/plugins/analysis/software_components/code/software_components.py line 43 if len(result) > 1: the 1 must be changed to a 0 because the summary is no longer in the same dict

src/test/unit/analysis/test_yara_plugin_base.py::TestAnalysisYaraBasePlugin

in src/test/unit/analysis/test_yara_plugin_base.py the functions test_process_object and test_process_object_nothing_found do not consider that the results are stored under the new 'result' key

@maringuu Since we decided to postpone this until Q1 2023 this should be marked appropriately. Also it will not be merged into database-migration anymore but either master or more likely a dedicated analysis dev branch.

Superseeded by #987 and its follow ups.
