add optinal request paramter named 'with_status' to /servers to list servers.

GET
/servers/detail
List Servers Detailed

For each server, shows server details including config drive, extended status, and server usage information.

But /servers/detail API is too slow when instance's number is greater than 1000.

Most of the time when we query all virtual machines, we not only want to get the UUID and name of the virtual machine, but also the status of the virtual machine. For the state of the virtual machine, we have to use detail.

I hope to modify /servers API to resolve the problem of querying the state of virtual machines is particularly time-consuming

/servers
List Servers

Lists IDs, names, and links for servers.

Add optional query parameter named with_status to /servers API， and return status to each servers in the response output.

for example:
request: /servers?with_status=true
response: list IDS, names, status, and links for servers.
