Issue details

Filter parsing seem to fail.
Additionally, the $filter param is duplicated as the library seems to add it (but it doesn't work also when omitting it).

Expected behavior

Return list of metrics.

Actual behavior

Reproduction Steps

cosmosClientFactory, err = armcosmos.NewClientFactory(subscriptionID, cred, nil)
	if err != nil {
		log.Fatal(err)
	}

	databaseAccountsClient = cosmosClientFactory.NewDatabaseAccountsClient()

	resourceGroupName := ...
	accountName := ...
	databaseId := ...
	containerId := ...

	metricsPager := databaseAccountsClient.NewListMetricsPager(resourceGroupName, accountName, "$filter=(name.value eq 'Total Requests') and timeGrain eq duration'PT5M' and startTime eq '2017-11-19T23:53:55.2780000Z' and endTime eq '2017-11-20T00:13:55.2780000Z", nil)
	for metricsPager.More() {
		page, err := metricsPager.NextPage(ctx)
		if err != nil {
			log.Fatal(err)
		}
		for _, metric := range page.Value {
			// Before reading a value, you MUST check that the pointer is not nil
			if metric.Name != nil && metric.Name.Value != nil {
				// Dereference the pointers with * to get the actual values
				metricName := *metric.Name.Value
				fmt.Printf("Metric: %s\n", metricName)
			}
		}
	}
