[Node manager] Uses huge amount of RAM on AWS
|Status:||In Progress||Start date:|

When node manager starts on AWS, it quicky uses a huge amount of RAM (2 GiB) despite not doing anything.
I've tracked this down to
arvnodeman.computenode.driver.ec2.ComputeNodeDriver._init_image_id which calls
libcloud.compute.drivers.ec2.BaseEC2NodeDriver.list_images. It seems that the problem is (a) it is listing a huge number of images (many thousands) and (b) it is retaining a lot of memory even for image records that should be GC'd.
We are currently using libcloud 0.16 on AWS which is an very out of date version.

The current version of libcloud is 1.2.1. We should definitely not be using a <1.0 release when 1.0+ is available.
