Bug 1858107

# Description of problem:
Starting the SmartState Analysis is not handled in consistent way across providers. 

### From `All datastores` page
Compute -> Infrastructure -> Datastores; [Select one RHV DS from the list], [Click on Configure -> Start SSA]

The button for starting the analysis of datastore on RHV providers is enabled, but the start is not sucesfull with message: "SmartState Analysis action does not apply to selected items". On vmware provider, the SSA starts fine.

### From Provider datastores page
Compute -> Infrastructure -> Providers; [Select RHV provider], [Select Datastores], [Check one DS from the list],  [Click on Configure -> Start SSA]

The SSA starts on datastore of both -- vmware as well as RHV. Message `... scan successfully initiated when trying from the datastore Details page" is displayed.`

### From Datastore `Details` page:
Compute -> Infrastructure -> Providers; [Select RHV provider], [Select Datastores from the table].

It seems no matter which navigation path is taken, The `Configure` button is disabled on RHV. It is enabled on vmware and works fine.


# Version-Release number of selected component (if applicable):
5.11.6.0.20200526234234_3fcafeb
5.11.7.0.20200714215453_0da8a4

# How reproducible:
1/1 For each CFME version noted.
It is important to note that when vmware provider is deleted, some items are archived, which can manifest as duplicated items (datastores for example) and that may cause a confusion.

# Steps to Reproduce:
1. Add a RHV and vmware provider
2. Go to datastore trough provider  and select it or select some DS from the All datastores page or display Details page of the datastore
3. Click on button for starting SSA

# Actual results:
When not going trough the provider, SSA is not allowed:
SmartState Analysis action does not apply to selected items
is displayed


# Expected results:
Hard to tell what should be expected. The compatibility matrix is not really populated for RHV in the documentation. The behaviour is not consistent even for single CFME version and single provider.
