add support for Route 53 - GetAccountLimit - Gets the specified limit for the current account

[vincentclee]

Feature Request

On the Route53 Service, add a call to GetAccountLimit which gets the specified limit for the current account, for example, the maximum number of health checks that you can create using the account.

Available Limits

• MAX_HEALTH_CHECKS_BY_OWNER: The maximum number of health checks that you can create using the current account.
• MAX_HOSTED_ZONES_BY_OWNER: The maximum number of hosted zones that you can create using the current account.
• MAX_REUSABLE_DELEGATION_SETS_BY_OWNER: The maximum number of reusable delegation sets that you can create using the current account.
• MAX_TRAFFIC_POLICIES_BY_OWNER: The maximum number of traffic policies that you can create using the current account.
• MAX_TRAFFIC_POLICY_INSTANCES_BY_OWNER: The maximum number of traffic policy instances that you can create using the current account. (Traffic policy instances are referred to as traffic flow policy records in the Amazon Route 53 console.)

Example

$ aws route53 get-account-limit --type MAX_HEALTH_CHECKS_BY_OWNER
{
    "Limit": {
        "Type": "MAX_HEALTH_CHECKS_BY_OWNER",
        "Value": 200
    },
    "Count": 179
}

Thank You
