Update getMMG() to use new condition code mapping format

[marcia-schulman]

There is a new format for the JSON information stored in Redis that maps condition/event codes to MMGs. The function needs to be updated to use the new format, which is under namespace "conditionv2:" in Redis.

New format example:

{
    "event_code": "50266",
    "name": "Salmonella enterica serotypes Paratyphi A, B (tartrate negative) and C (S. Paratyphi) infection",
    "program": "NCEZID",
    "category": "Enteric Diseases",
    "profiles": [
        {
            "name": "FDD_MMG_V1.0",
            "mmgs": ["mmg:FDD_Typhoid_and_Paratyphoid"],
            "special_cases": [
                {
                    "applies_to": "foodnet_states",
                    "mmgs": ["mmg:FDD_Typhoid_and_Paratyphoid", "mmg:FoodNet"]
                }
            ]
        },                                                      
        {
            "name": "FDD_MMG_V2.0",
            "mmgs": ["mmg:FDD_V2.0_FN_S_Typhi_S_Paratyphi"],
            "special_cases": [
                {
                    "applies_to": "foodnet_states",
                    "mmgs":  ["mmg:FDD_V2.0_FN_S_Typhi_S_Paratyphi", "mmg:FoodNet"]
                }
            ]
        }
    ]
}

@marcia-schulman can you put an estimate on this?
