CLOUDSTACK-4904: Unable to see a derieved template if the
 parent template is deleted. Modified template_view so that removed(or InActive) templates also be there in the view.
Previous behavior of listing templates and state column in vm_templates will be the same.
CLOUDSTACK-5853
Create two storage pools, one with storage tag X, one with storage tag Y.
Create a service offering with storage tag X.
Create a disk offering with storage tag Y.
Attempt to deploy a virtual machine with a datadisk, using given offerings, it fails.

Deployment planner keeps a global object 'avoid'. It loops through each volume to
be created, asking storage allocators for matching pools, passing this avoid object.

First disk matches a pool or pools, adds ALL other pools to avoid object, then
deployment planner attaches matching pools to a list for that disk.

Second disk matches a pool, adds all other pools to avoid object, then deployment
planner says "wait, matching pool is in avoid, can't use it". Oops. In fact, at this
point ALL pools are in avoid (unless there are other pools that have both tags).

Need to remove matching pool from the avoid set during each select phase.
