fixes #20652 - moved compute_resource js code to webpack

this creates a new namespace under tfm, tfm.computeResource
where relevant functions are expoed under the compute resource
namespace, for example:

tfm.computeResource.ovirt.termplateSelected function

Additional common functions are also exposed under the same namespace:

tfm.computeResource.providerSelected

I left the host form NIC code out of this PR as it actually requires
code changes, changes in this PR are comsetic (mostly linting) and
convertion to ES6.
