Parseable optargs

[NotJustAnna]

What is this?

Make a list of optargs K/V allowed values, preferably in JSON.

Example:

{
    "optarg_enums": {
        "E_FORMAT": ["raw", "native"],
        "E_DURABILITY": ["hard", "soft"],
        "E_CONFLICT": ["error", "replace", "update"],
        "E_READ_MODE": ["single", "majority", "outdated"],
        "E_IDENTIFIER_FORMAT": ["name", "uuid"],
        "E_BOUND": ["open", "closed"],
        "E_STATUS": [
            "ready_for_outdated_reads",
            "ready_for_reads",
            "ready_for_writes",
            "all_replicas_ready"
        ],
        "E_EMERGENCY_REPAIR": [
            "unsafe_rollback",
            "unsafe_rollback_or_erase"
        ],
        "E_RESULT_FORMAT": [
            "text",
            "json",
            "jsonp",
            "binary",
            "auto"
        ],
        "E_HTTP_METHOD": [
            "GET", "POST", "PUT", "PATCH", "DELETE", "HEAD"
        ],
        "E_AUTH_TYPE": ["basic", "digest"],
        "E_GEO_SYSTEM": ["WGS84", "unit_sphere"],
        "E_UNIT": ["m", "km", "mi", "nm", "ft"]
    },
    "global_optargs": {
        "use_outdated": "T_BOOL",
        "time_format": "E_FORMAT",
        "profile": "T_BOOL",
        "durability": "E_DURABILITY",
        "group_format": "E_FORMAT",
        "noreply": "T_BOOL",
        "db": "T_DB",
        "array_limit": "T_NUM",
        "binary_format": "E_FORMAT",
        "min_batch_rows": "T_NUM",
        "max_batch_rows": "T_NUM",
        "max_batch_bytes": "T_NUM",
        "max_batch_seconds": "T_NUM",
        "first_batch_scaledown_factor": "T_NUM"
    }
}

Things to keep in mind

According to srh:

You can actually use term optargs in the global optargs (and they apply to any term that uses them). Which IMO is unfortunate, but that's life.
