(DIO-908) Floaty can now report the status of ABS requests

- If ABS queries returns a body for 200 or 202, floaty will print it
this is useful in the new version of ABS, since it shows the progress
for ondemand requests (AWS or vmpooler)
- removed the queue_place and querying the queue for a 'get' request
this queue_place number was misleading since it was just a redis index
and did not represent well where the request was in the queue
- Also added a flag option --continue to be used when the cli was
interrupted for example with ctrl-c
