Remove dialog seeding because it's not needed.

Replace dialog seeding with factory in vmdbws_provisioning_spec.

Replace dialog seeding with miq_dialog_provision factory.

Added root_password content to miq_dialog_provision factory to allow
testing encryption of specific fields.

Total time across these specs dropped from 6.1s to 3.47s. WAT
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"]
```
Global replace of sequence "...#{n}" to ensure padding for ABC sorting.
