etag generation fails if 'uuidRepresentation' is not set in MONGO_OPTIONS

Expected Behavior

When uuidRepresentation is not set in MONGO_OPTIONS generating etags should still be possible.

-- app.py
my_settings = {
    'MONGO_HOST': 'localhost',
    'MONGO_PORT': 27017,
    'MONGO_DBNAME': 'the_db_name',
    'DOMAIN': {'contacts': {}}
}

app = Eve(settings=my_settings)
app.run()


-- some_test.py
from eve import post_internal
post_internal('contacts', {'a_valid_contact': 'this must be'}, skip_validation=True)

Actual Behavior

Since no uuidRepresentation is present in MONGO_OPTIONS, the default option is selected, which is an int, not a string. A simple fix would be changing line 350 in eve/utils.py from config.MONGO_OPTIONS.get("uuidRepresentation", UuidRepresentation.STANDARD) to config.MONGO_OPTIONS.get("uuidRepresentation", "standard")

or add a field 4 to the uuid_map on line 343:

uuid_map = {
            "standard": UuidRepresentation.STANDARD,
            4: UuidRepresentation.STANDARD,
            "unspecified": UuidRepresentation.UNSPECIFIED,
            "pythonLegacy": UuidRepresentation.PYTHON_LEGACY,
            "csharpLegacy": UuidRepresentation.CSHARP_LEGACY,
            "javaLegacy": UuidRepresentation.JAVA_LEGACY,
        }

    def uuid_representation_as_string():
        uuid_map = {
            "standard": UuidRepresentation.STANDARD,
            "unspecified": UuidRepresentation.UNSPECIFIED,
            "pythonLegacy": UuidRepresentation.PYTHON_LEGACY,
            "csharpLegacy": UuidRepresentation.CSHARP_LEGACY,
            "javaLegacy": UuidRepresentation.JAVA_LEGACY,
        }
>       return uuid_map[
            config.MONGO_OPTIONS.get("uuidRepresentation", UuidRepresentation.STANDARD)
        ]
E       KeyError: 4

Environment

• Python version: 3.9.2
• Eve version: 2.0.1

A workaround for this bug is to simply set uuidRepresentation to 'standard' in MONGO_OPTIONS
