UpdatePoolMembers (replace-all-with) adds nodes with monitor up / sessions enabled

[mattdgsg]

I'm honestly not sure if this is an issue with go-bigip or the iControl REST interface, but when I do a replace-all-with pool modification via tmsh, the new pool members have the following availability / states:

| Availability : unknown
| State : enabled
| Reason : Pool member service checking is enabled, but result is not available yet
| Monitor Status : checking
| Session Status : enabled

This is what I would expect; the BigIP hasn't performed a health check, yet. But for some reason when I do an UpdatePoolMembers via go-bigip, the new pool members have the following availability / states:

| Availability : available
| State : enabled
| Reason : Pool member is available
| Monitor Status : up
| Session Status : enabled

Is this expected? Why the difference?
