Populate all the fields in the status endpoint

#### Check for a solution in the Azure portal
Sample output from status endpoint of FC application - https:///admin/host/status
```
{
"id": "db9851c42a24286354a628e488c2790f",
"state": "Running",
"version": "4.25.2.2",

}
```
`computerName` `platformVersion` need to be populated for FC apps

Start with the /admin/host/status endpoint and compare its response with the sample output and the Azure portal for a Flex Consumption application. Trace where computerName and platformVersion are sourced, then verify that both fields are populated for FC apps and that existing status fields remain unchanged.
