refactor: unit tests DATA variables to be dictionaries

[mtache]

Currently, the unit tests DATA variables are list[AntaUnitTest]. This has led to duplicates in the past.

class AntaUnitTest(TypedDict):
    """The parameters required for a unit test of an AntaTest subclass."""

    name: str
    test: type[AntaTest]
    inputs: NotRequired[dict[str, Any]]
    eos_data: list[dict[str, Any] | str]
    expected: Expected

We should refactor the DATA variables to be dict[Tuple[type[AntaTest], str], AntaUnitTest] instead where AntaUnitTest is:

class AntaUnitTest(TypedDict):
    """The parameters required for a unit test of an AntaTest subclass."""

    inputs: NotRequired[dict[str, Any]]
    eos_data: list[dict[str, Any] | str]
    expected: Expected

DATA: list[AntaUnitTest] = [
   {
        # Arbitrary test name.
        "name": "success",
        # Must be an AntaTest subclass definition
        "test": VerifyUptime,
        # JSON output of the 'show uptime' EOS command as defined in VerifyUptime.commands
        "eos_data": [{"upTime": 1186689.15, "loadAvg": [0.13, 0.12, 0.09], "users": 1, "currentTime": 1683186659.139859}],
        # Dictionary to instantiate VerifyUptime.Input
        "inputs": {"minimum": 666},
        # Expected test result
        "expected": {"result": "success"},
    },
    {
        "name": "failure",
        "test": VerifyUptime,
        "eos_data": [{"upTime": 665.15, "loadAvg": [0.13, 0.12, 0.09], "users": 1, "currentTime": 1683186659.139859}],
        "inputs": {"minimum": 666},
        # If the test returns messages, it needs to be expected otherwise test will fail.
        # The expected message can be a substring of the actual message.
        "expected": {"result": "failure", "messages": ["Device uptime is 665.15 seconds"]},
    },
]

DATA: dict[Tuple[type[AntaTest], str], AntaUnitTest] = {
   (VerifyUptime, "success"): {   # First element is an AntaTest subclass definition and the second an arbitrary test name.
        # JSON output of the 'show uptime' EOS command as defined in VerifyUptime.commands
        "eos_data": [{"upTime": 1186689.15, "loadAvg": [0.13, 0.12, 0.09], "users": 1, "currentTime": 1683186659.139859}],
        "inputs": {"minimum": 666},  # Dictionary to instantiate VerifyUptime.Input
        # Expected test result
        "expected": {"result": "success"},
    },
    (VerifyUptime, "failure"): {
        "eos_data": [{"upTime": 665.15, "loadAvg": [0.13, 0.12, 0.09], "users": 1, "currentTime": 1683186659.139859}],
        "inputs": {"minimum": 666},
        # If the test returns messages, it needs to be expected otherwise test will fail.
        # The expected message can be a substring of the actual message.

    },
