When cloning DS assignments from one cache to another, target cache list is incomplete

[mitchell852]

https://tp.domain.net/#!/servers/:id/delivery-services under More provides the ability to clone ds assignments from one cache to another, however, the target cache list is incomplete as the dropdown in this view:

is populated via this API call:

GET api/1.3/servers?type=EDGE

This is problematic because the system allow the addition of caches types such as:

EDGE_FOO

so currently, the targets list is limited to type=EDGE and you can't clone ds assignments from one EDGE_FOO cache to another EDGE_FOO cache.
