Remove root object logging from service class update status method.
Use active_record_instance_double for MiqServer instance stub
Modified class schema entries and methods for status_state change.

Removed references to status_state on update_*_status method calls and
modified methods to get new root attribute instead of input value.
Set new workspace root attribute ae_status_state to method name.

The on_entry, on_exit, and on_error state machine methods usually
pass 2 required parameters to the update_*_status methods; status
and status_state. The addition of this new attribute will negate the
need to pass status_state, simplifying the method calls.

SCVMM scheduled EMS refresh.

A mechanism was needed to refresh the SCVMM provider given that event support will not be in the 3.1 release. I have configured a 4 minute schedule but am open to negotiation on the frequency. On one hand we need to bear in mind that an EMS refresh can take more than 4 minutes but on the other hand we can't wait too long after a VM power operation.
