[Azure.Monitor.Query] Suppress QueryTimeRange in MetricsQueryResourcesOptions

[nisha-bhatia]

Currently, https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/monitor/Azure.Monitor.Query/src/MetricsQueryResourcesOptions.cs#L20 MetricsQueryResourcesOptions takes in a QueryTimeRange TimeRange property.
Using this parameter is confusing as it has three parts: duration, starttime, and endtime. The service only takes in starttime and endtime so we should make TimeRange as EditorBrowseableNever and add two new properties: Starttime and Endtime.

With 3 parameters on QueryTimeRange, here are all the combinations and their outcomes:

1. StartTime and EndTime not set -> service defaults to one hour
2. StartTime specified -> service sets EndTime to be current Time
3. StartTime and EndTime both set -> works
4. Duration needs to be passed in (because of the QueryTimeRange constructor) but is disregarded
