[WIP] Fix issues with iFramed cluster pages

[mantis-toboggan-md]

3 open issues all related to rendering the wrong iframed Ember page, or rendering the page with missing content:
#12506
#12541

possibly #12339

The code used to determine which component to render when editing any given type of cluster is convoluted. There are inexplicable mappings required to keep iframed ember pages functional (why must aks map to azureaks? why is the provider query param sometimes import and sometimes imported? Why is there an importProvider query param not used on imported clusters?) I am not even sure the above 3 issues have exactly the same root cause, but this area of dashboard code is so convoluted and prone to churn, I think they need to be addressed in tandem.

I think the above bugs came in via some combination of this and this PR. Limiting the scope of those changes seems to address #12506 and #12541 but not fully #12339 ( with this PR, I see the ember page as expected, but the 'mode' is wrong, create button shown instead of save)

Because I think the bugs are conntected to ember query params, I've collected data on the fields used to generate those query params, and what those query params are in 2.9-head ember standalone world - ember standalone has been removed from 2.10 but we can assume that these are the correct params the dashboard should be passing to ember. All below fields are on the relevant management cluster object, not the provisioning cluster object. If providerForEmberParam needs to be fixed, we need to verify that given the below status/config fields, the correct provider and importProvider query params are still set in every scenario.

cluster type	status.provider	status.driver	spec.aksConfig/eksConfig/gkeConfig.imported	ember provider qp*	ember importProvider qp*
local rke1	rke	imported	n/a	import	other
local rke2	rke2	rke2	n/a	import	other
local k3s	k3s	k3s	n/a	k3s	undefined
local hosted (eks)	eks	imported	undefined	import	other
local MB ovh-downstream test cluster**	''	imported	undefined	import	other
rke1 provisioned	'rke'	rancherKubernetesEngine	n/a	digitalocean	undefined
rke2 provisioned	rke2	imported	n/a	n/a	n/a
k3s provisioned	k3s	imported	n/a	n/a	n/a
hosted provisioned (aks)	aks	AKS	false	n/a	n/a
rke1 imported	rke	imported	n/a	imported	undefined
rke2 imported	rke2	rke2	n/a	rke2	undefined
k3s imported	k3s	k3s	n/a	k3s	undefined
hosted imported (aks)	aks	AKS	true	azureaks	undefined
3rd party kontainer provisioned	''	ovhcloudmks	n/a	ovhcloudmks	undefined

* undefined => an iframed page should be used for this cluster, but this query param should be present; n/a=>iframed ember pages should not be used for this cluster
** need to find out what this cluster actually is

Regarding ovh, once I get the right page to render I am seeing a console error that could be related

This would need a back port to v2.10.x -- .0 ideally but we're running out of time.

Because this all appears to be working in 2.9 I decided to diff dashboard between master and 2.9.

When diffing master with 2.9 I saw #12177 and when reverting it seems to resolve the issues we're having with editing. The above pr was created in response to #9868.

I'm leaning toward reverting #12177 and changing the fix for #9868 because ultimately it supposed to update a display property but seems to be having cascading consequences. I'll see if I can have some luck going down this path.
