[WIP] Move provisioning quota calculation methods into MiqTemplate class (pluggable)

[jaywcarman]

PR set:

• Move provisioning quota calculation methods into MiqTemplate class (pluggable) manageiq-content#737
• Move provisioning quota calculation methods into MiqTemplate class (pluggable) manageiq-automation_engine#532
• Override quota calculation methods manageiq-providers-ibm_cloud#469
• Override quota calculation methods manageiq-providers-ibm_power_hmc#146

Fixes #22641

Move methods making quota calculations for a given request into MiqTemplate base class. They can then be overridden in the ManageIQ::Providers::CloudManager::Template subclass (for "cloud" providers), or even in provider plug-in subclasses.

Allows an override in ManageIQ::Providers::IbmCloud::PowerVirtualServers::CloudManager::Template to fix a bug where it reports 0 cpus for quota.

TODO:

• Fix faililng cross-repo tests
• Make storage calculations pluggable

@jaywcarman Sorry, having trouble making out what was changed

Is it possible to change this into 2 (or more) commits?
When it makes sense, separating move operations from change operations:

1. Move code into MiqTemplate unchanged.
2. Move code into infra/template and cloud/template.

@kbrock I'm happy to do so.
