What:
This PR adds displaying Tenant name in Providers, Automate Domain and Services. Tenant name will be displayed with this PR in Summary View of cloud or infra provider, in Relationships table. Also a new column with the Tenant name will be displayed in the List view of a Provider, Automate Domain or a Service Catalog Item/Catalog Bundle (it will not be included in: Grid View, Tile View, Dashboard view).

How to test:

• For providers:
  Compute -> Infrastructure/Clouds -> Provider
  and choose some provider if you want to check the Summary view
• For Automate Domain:
  Automation -> Automate -> Explorer
• For Services:
  _Services -> Catalogs -> Catalog Items -> choose some Catalog Item/Catalog Bundle

TODO:

• display Tenant name in Summary View of any provider, in Relationships table
• display Tenant name as a new column in list view of providers
• hide Tenant name from the list view of providers if user is not admin
  (we need Hide columns in GTL lists for non-admin users(not only) #5616 and Modify method to hide columns dynamically in GTL list manageiq#18812)
• add column Tenant name for Automate Domain
• add column Tenant name for Service Catalog Items/Catalog Bundles (Summary screens)
• specs

Note:
Tenant names are displayed only for admin users.

The field should be either in cols or under include, not both.

(so, just include, col_order and headers for this one)
(same in the other yaml)

The part that is "pending core" was moved to a separate PR.
