Setting offer throughput or autopilot on container is not supported for serverless accounts

[tomgron]

When trying to create a collection in a serverless CosmosDb I get this error :

2021-03-10T04:32:56.3140412Z ##[error]Setting offer throughput or autopilot on container is not supported for serverless accounts.

I believe the "Throughput" setting in the task should be optional if one uses serverless version of CosmosDb to be used.

Maybe this line should be changed from default 400 (as throughput) to something else:

vsts-tasks/cosmosdb-tasks/Tasks/CosmosDBCollectionManagement/cosmosdb.ts

Line 52 in fb39155

let offer = (throughput == null || throughput.length === 0) ? 400 : Number(throughput);
