[Preview] AI Integration: Adds latency based filters to add request diagnostics in Activity and some minor changes

Description

As part of this PR,

1. Ways to set global Latency threshold:

a) Using Client Builder:

CosmosClientBuilder cosmosClientBuilder = new CosmosClientBuilder(
                accountEndpoint: endpoint,
                authKeyOrResourceToken: key).WithDistributingTracingOption(new DistributedTracingOptions
                {
                    LatencyThresholdToIncludeDiagnostics = TimeSpan.FromMilliseconds(100)
                });

b) Using Client Options:

CosmosClient cosmosClient = new CosmosClient(
        "account-endpoint-from-portal", 
        "account-key-from-portal", 
        new CosmosClientOptions()
        { 
         EnableDistributedTracing = true,
         DistributedTracingOptions = new DistributedTracingOptions
                {
                    LatencyThresholdToIncludeDiagnostics = TimeSpan.FromMilliseconds(100)
                }
});

c) Using Request Options:

ItemRequestOptions requestOptions = new ItemRequestOptions { 
               DistributedTracingOptions= new DistributedTracingOptions
                {
                    LatencyThresholdToIncludeDiagnostics = TimeSpan.FromMilliseconds(100)
                }
};
ItemResponse<ToDoActivity> createResponse = await container.CreateItemAsync<ToDoActivity>(testItem, requestOptions: requestOptions);

2. Default Latency threshold has been set from Query and Non-Query operations
   

In Java SDK, for Query operations it is 500ms, but in previous PRs, we decided to have threshold as 250ms in .Net SDK.
3. Changes the namespace name to Microsoft.Azure.Cosmos.Telemetry and fix corresponding imports.
4. Changed message to "information not available" from NA if information is not available.
5. Check Scope enablement before recording any value to avoid any precalculation overhead which we might be happening before setting attribute value.
6. Remove EnableOpenTelemetry API and Add internal EnableOpenTelemetrySupport API to enable this feature only in preview build and for GA build internal package like tests can enable it on demand
7. Add Account Host information instead of Account Name along with Cloud information in net.peer.name attribute.
8. Populate Database and Container information on Create Container calls
9. Populate Database information on Create Database Calls.

Type of change

• [] New feature (non-breaking change which adds functionality)

Just for my understanding, under what conditions will diagnostics be set to null?

ReadThroughputIfExistsAsync is one of the functions where diagnostics will be null.
