Cosmos: Expose retry policy options

[AndriySvyryd]

The retry policy built into the SDK now handles all safe-to-retry queries: https://docs.microsoft.com/en-us/azure/cosmos-db/troubleshoot-dot-net-sdk?tabs=diagnostics-v3#retry-logic-

• Expose related SDK configuration in the provider options: ApplicationPreferredRegions, MaxRetryAttemptsOnRateLimitedRequests, MaxRetryWaitTimeOnRateLimitedRequests, AllowBulkExecution
• Consider removing default retrying strategy on write operations as some are handled by the retry policy https://github.com/Azure/azure-cosmos-dotnet-v3/blob/master/Microsoft.Azure.Cosmos/src/ClientRetryPolicy.cs#L313
• Add documentation
