[Feature] testflinger cli could report status of a queue (summary of incomplete jobs) #116
Description
CLI is the primary interface to testflinger, and even if we implement some way to launch jobs from a web page, often CLI is the best way to interact with testflinger.
I find that I sometimes launch up to 80-100 jobs in sequence to pressure test systems. This, obviously, takes a very long time to complete 80 - 100 jobs against a machine, and currently my only real way of knowing that the queue 'fleep' is either running a job, or is completely finished, is polling each job, or running a loop against every known job ID I've created to get a status. It is a bit painful to check all the fleep job-ids and have to wade through 70 "Completed" just to get to 71 "Provisioning" and 72-80 "Waiting".
It would be nice to get a summary of jobs (since we CAN look here: https://testflinger.canonical.com/jobs and see a long list of job IDs and the associated queues) via CLI for just the single requested queue.
Something like this:
$ testflinger-cli queue-status fleep
70 complete, 1 Running, 9 Waiting
$ testflinger-cli queue-status --verbose fleep
75 complete, 1 Running, 4 Waiting

--verbose --show-completed would list all the completed jobs that TF still has info for (e.g. the ones that haven't aged out and results/artifacts are still available, with the assumption that anything older you really don't care about at all)
