resource/aws_servicequotas_service_quota: Check for presence of ErrorReason and Value when checking quota value

[gdavison]

Some services, such as Elastic Load Balancing have additional permissions required to read quota values. If the IAM principal accessing trying to read the quota is permitted to read servicequotas:GetServiceQuota but does not have the additional permission, the resource currently updates the current value to 0 rather than failing.

The AWS CLI returns the following with permissions:

$ aws service-quotas get-service-quota --service-code elasticloadbalancing --quota-code L-53DA6B97 --region us-east-1
{
    "Quota": {
        "ServiceCode": "elasticloadbalancing",
        "ServiceName": "Elastic Load Balancing (ELB)",
        "QuotaArn": "arn:aws:servicequotas:us-east-1:123456789012:elasticloadbalancing/L-53DA6B97",
        "QuotaCode": "L-53DA6B97",
        "QuotaName": "Application Load Balancers per Region",
        "Value": 100.0,
        "Unit": "None",
        "Adjustable": true,
        "GlobalQuota": false
    }
}

When the IAM principal does not have access:

$ aws service-quotas get-service-quota --service-code elasticloadbalancing --quota-code L-53DA6B97 --region us-east-1
{
    "Quota": {
        "ServiceCode": "elasticloadbalancing",
        "ServiceName": "Elastic Load Balancing (ELB)",
        "QuotaArn": "arn:aws:servicequotas:us-east-1: 123456789012:elasticloadbalancing/L-53DA6B97",
        "QuotaCode": "L-53DA6B97",
        "QuotaName": "Application Load Balancers per Region",
        "Unit": "None",
        "Adjustable": true,
        "GlobalQuota": false,
        "ErrorReason": {
            "ErrorCode": "DEPENDENCY_ACCESS_DENIED_ERROR",
            "ErrorMessage": "You don’t have access to elasticloadbalancing:DescribeAccountLimits"
        }
    }
}
