nodepool: lower task ratelimiting from 10 to 1 sec
Whenever Nodepool as to interact with the OpenStack API, it creates a
task that is inserted in a queue. The task manager process one at a time
and has a built in rate limiting to avoid overflowing the OpenStack API.
I originally had set the limiter to 10 seconds since I had little
understanding of its effect. Since instances deletions are a task,
Nodepool can delete at most an instance every 10 seconds or 6 per
minutes.
Nodes creations are not affected and are not rate limited.
Set rate throttler from 10 seconds down to 1 second.
