Remove X-Auth-Token from HP temporary signing

HP Cloud does not use X-Auth-Token for temporary signed URLs and
leaking this allows clients arbitrary privileges until token timeout.

Remove InputSuppliers.of(byte[])

Callers rarely want this functionality and should call
ByteStreams.newInputStreamSupplier when they do.

Issue 1103: isolate polling of nodes into its own class
Improved ComputeService and delegate virtual datacenter election to TemplateBuilder

Made a few changes to adapt the Abiquo compute service
implementation to the most common use cases:

* Do not attempt to create a VDC. Regualr users may not have
  permissions to create VDCs, so don't try to create them. A
  VDC compatible with teh template being deployed must exist.
* Configure nodes with one public ip by default, and if no
  public ip is available, assign one from the default private
  VLAN for the selected virtual datacenter.

Also fixed some concept mappings between Abiquo and jclouds:

Virtual datacenter (zone) election should be performed by the
TemplateBuilder and not by the ComputeServiceAdapter. This commit
refactors the current adapter to implement the right behavior.

The two main concepts in this refactor are about locations. Now,
physical datacenters will be scoped to Region locations, and virtual
datacenters to Zones.

Images in Abiquo are scoped to Regions (each physical datacenter has a
set of available images), and hardware profiles will be used to scope
images to a particular virtual datacenter. Since a virtual datacenter in
Abiquo is just a container that provides compute resources in a specific
virtualization technology, each image will have one hardware profile
scoped to each compatible virtual datacenter (zone).

This way, the virtual datacenter election will be made using the
TemplateBuilder, by selecting the desired hardware profile.
Prefer immutable over empty collections

The former does not create an object when calling iterator(), as
discussed here:

Applied fixes suggested in last review

Renamed VirtualMachineTemplateWithZone to
VirtualMachineTemplateInVirtualDatacenter and encoded the id using a
slash instead of the hyphen.
