azure-pipelines-tasks: Validation during AzureFunctionApp Task takes too long

Type: Question

Enter Task Name: AzureFunctionAppV1, AzureFunctionAppV2

Issue Description

Both of these tasks take a long time (e.g. 13 minutes) just for the validation step to complete.

https://github.com/microsoft/azure-pipelines-tasks/blob/30c99c8a7013d012f14c129e8ee212c7c622008a/Tasks/AzureFunctionAppV2/azure-arm-rest/azure-arm-app-service-kudu.ts#L653

This is the call that takes so long for no apparent reason. Is this potentially a bug or what could be the cause?
