[Azure Metrics] the integration fails with the "metric names configured CassandraConnectionClosures are not supported for the resource" error

[zmoog]

I recreated the following customer issue on my test cluster and got the same error:

{
    "error.message": "the metric names configured  CassandraConnectionClosures are not supported for the resource /subscriptions/c21791dd-861f-49ce-9d7b-57ed772bb3e8/resourceGroups/my-rg/providers/Microsoft.DocumentDb/databaseAccounts/whatever/Microsoft.DocumentDb/databaseAccounts"
}

The name of the metric, "CassandraConnectionClosures" is listed in the wrong section of the metrics configuration. It should be moved to a different section that includes metric names which may or may not be available depending on the environment, with the "ignore_unsupported" setting set to true.

A fix for this problem is available in the Azure Metrics integration starting from version 1.0.14.

There’s a similar fix for Metricbeat in a PR, but it’s not merged yet.

I will try to finish the PR and make it ready for review ASAP.
