### 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)
}
}
}
```
