First version of cache builder and lookup logic for live validation

[vishrutshah]

• Clones git repository from configurations
• Read all the swagger spec files and parse them
• Create an in memory cache for all the operations across all the swagger specs based on below structure:

{
  "api-version1":
  {
    "provider1": 
     {
        "get": [ {opeationObject(Sway)}, {operationObject(sway)}, . .  ],
        "post": [ {opeationObject(Sway)}, {operationObject(sway)}, . .  ],
        "put": [ {opeationObject(Sway)}, {operationObject(sway)}, . .  ],
        ...
     }
  },
  "api-version2":
  {
    "provider2": 
     {
        "delete": [ {opeationObject(Sway)}, {operationObject(sway)}, . .  ],
        "head": [ {opeationObject(Sway)}, {operationObject(sway)}, . .  ],
        "get": [ {opeationObject(Sway)}, {operationObject(sway)}, . .  ],
        ...
     }
  },
  . . .
}

• Expose getPotentialOperations for lookup for best match on regex of path

Part of #89 & #90
