Move remaining aggregate operations to conductor

This patch moves the following aggregate operations from compute
to conductor:

  aggregate_get_by_host()
  aggregate_metadata_add()
  aggregate_metadata_delete()

In order to do that, it also changes the signature of the corresponding
VirtAPI methods to take the aggregate object instead of just the id,
so that we don't re-introduce any db messaging behavior.

I debated about using the set_delete mechanism in the metadata_add
API to avoid adding a separate conductor API for delete, but decided
that it wasn't worth the extra round trips, no matter how much I may
wish it were.
