pass the column type for the join column to references

this is the same API that is supported on master, so we can upgrade
this more easily
Replace dialog seeding with miq_dialog_host_provision factory.

Marked the one test as no longer pending because although we may not
support host provision from the webservice, the from_ws method is a
valid entry point and through that entry point, host provisioning should
be working.

The confusion comes from the name of the method from_ws, which by name
sounds web-servicey, but really it's just a generic entry point with
parameters. It was written for web services initially, but it's really
just a proper interface method, that could be used by anything. We
should rename that method in a separate commit.

Total time for this spec dropped from 3.47s to 2.4s and we ADDED a test.

Storage naming caused the sort_by to sort storage_9 after storage_10.

See build_smartproxy_affinity_node:
https://github.com/ManageIQ/manageiq/blob/e405e1ad52072a0c7f341481d6457841e849450e/vmdb/app/controllers/ops_controller/settings/common.rb#L1272

This fixes a sporadic test failure where the storages are in an unexpected order because the sequencing created storages with names that didn't always sort in the same order as their creation order.

Before:

```
["storage_2", "storage_1", "storage_10", "storage_9"].sort
=> ["storage_1", "storage_10", "storage_2", "storage_9"]
```

After:
```
["storage0000000000002", "storage0000000000001", "storage0000000000010", "storage0000000000009"].sort
=> ["storage0000000000001", "storage0000000000002", "storage0000000000009", "storage0000000000010"]
```
