FIX: Chang the timing about calling logAnalytics.Post

[miyagin15]

I want to merge this change because this code posts many requests and the wrong JSON to the logAnalytics.

Before the code call API each resource. These are some example JSONs posted to the logAnalytics.

1. first call: [ {"PreTaxCost": {cost},"Date": "{sDate}","ResourceId": "{sResourceId}","ResourceType": "{sResourceType}","SubscriptionName": "{sSubscriptionName}","ResourceGroup": "{sResourceGroup}"}]
2. second call: [{"PreTaxCost": {cost},"Date": "{sDate}","ResourceId": "{sResourceId}","ResourceType": "{sResourceType}","SubscriptionName": "{sSubscriptionName}","ResourceGroup": "{sResourceGroup}"}]
   $",{"PreTaxCost": {cost},"Date": "{sDate}","ResourceId": "{sResourceId}","ResourceType": "{sResourceType}","SubscriptionName": "{sSubscriptionName}","ResourceGroup": "{sResourceGroup}"}]
   ...
