Improve verbosity

[develop-cs]

Is your feature request related to a problem? Please describe

The current verbose mode contains information about "Why rule ABC was activated?". However, we often need information about "Why rule ABC was NOT activated?".

Describe the solution you'd like

Upgrade the verbosity data.

Before :

{
      "verbosity": {
          "rule_set": "second_rule_set",
          "results": [
              {
                  "rule_group": "admission",
                  "verified_conditions": {
                      "condition": {
                          "expression": "HAS_SCHOOL_AUTHORIZED_POWER",
                          "values": {"HAS_SCHOOL_AUTHORIZED_POWER": True},
                      },
                  },
                  "activated_rule": "ADM_OK",
                  "action_result": {"admission": True},
              },
      },
}

After :arrow_right: unverified_conditions key :

{
        "verbosity": {
            "rule_set": "second_rule_set",
            "results": [
                {
                    "rule_group": "admission",
                    "unverified_conditions": {
                        "condition": {
                            "expression": "HAS_SCHOOL_AUTHORIZED_POWER and HAS_CUSTOM_POWER",
                            "values": {"HAS_SCHOOL_AUTHORIZED_POWER": True, "HAS_CUSTOM_POWER": False},
                        },
                    "verified_conditions": {
                        "condition": {
                            "expression": "HAS_SCHOOL_AUTHORIZED_POWER",
                            "values": {"HAS_SCHOOL_AUTHORIZED_POWER": True},
                        },
                    },
                    "activated_rule": "ADM_OK",
                    "action_result": {"admission": True},
                },
        },
}
