Query global projects when get/list'ing compute images.

This patch refactors some of the code that would query global
projects when get'ing images. It makes the list of global projects
a constant on the Images collection, so that both 'get' and 'list'
can use the same list of projects to query.

Also, when bootstrapping/create'ing a server, the validation of
the specified image name is done by trying to 'get' the image
instead of 'save'ing it.

[AWS|ASG] filter mocked results for describe_auto_scaling_policies

This is the same issue as was fixed for ASGs in #2040 / de274452

Because Policies#get uses this method to fetch a single Policy, it was
always returning the first Policy in the data set, not the one that
actually matched the specified Policy name. Likewise, providing a filter
for `AutoScalingGroupName` did not actually filter the returned data
from this call when mocked.
