Refs #22620 - make UI honor enabled repo types

[jlsherrill]

This adds more awareness around what repo types are
enabled, on the lifecycle env page, the main navigation,
and updates detection on the new repo page

Issues: #22620

[jlsherrill]

requires Katello/bastion#223

[akofink]

Getting the same error locally as the CI:

NameError: uninitialized constant Katello::RepositoryTypes

Is this PR WIP?

[jlsherrill]

@akofink sorry, had a mistake, updated.

[akofink]

Hrm... now, when trying to create a new repository, the 'Type' dropdown list is empty. There are no JS errors. Are you seeing this?

[jlsherrill]

@akofink sorry about that, updated.

[akofink]

APT! It now works as expected.

[jlsherrill]

@akofink please retest this. This did a couple of things:

Fixed the global nav, it wasn't hiding nav items based on enabled repo types
adding controlling of enabled content types via a configuration (katello.yml) see updates to the example

code changes

[akofink]

Works as expected. A bit of IRC discussion:

  akofink | I have all the content types turned off :)
jsherrill | hehe
  akofink | I like how it still shows me content that I synced, even though it's turned  off
        ⤷ | That's intentional, right? On the lifecycle environments page
        ⤷ | seems so from the code
jsherrill | akofink: yeah
        ⤷ | when possible we try to just go off what you've synced
        ⤷ | so the ui gets easier to use the fewer types of content you've synced
        ⤷ | the content view versions page does this already
        ⤷ | content view version details i mean
  akofink | but it can be a bit weird because I can see my existing yum repos, but I can't make any new ones :)
jsherrill | yeah
        ⤷ | normally you'd just define what types you want at install time
        ⤷ | (PRs to come)
        ⤷ | and not turn them off willy-nilly
  akofink | It seems like a use case that users wouldn't get into. If they wanted to stop using yum, step 1 would be delete all the yum repos
        ⤷ | then disable it
        ⤷ | jsherrill: what I don't like is, I can still sync my yum repo successfully
jsherrill | akofink: well the goal is really to be able to install katello without support for one or more content types
  akofink | jsherrill: I'm fine with it as is, if you think the use case will be to disable from installation. Just know that someone somewhere will do what I just did and have questions.
          | ;)
jsherrill | yeah, its good to know the limitations :)
        ⤷ | and potential questions

[akofink]

I think you should put some comments. Namely that the default is that all registered content types are allowed. Optionally, that the Katello repository types are located and registered from /lib/katello/repository_types/*.rb.

[akofink]

I mostly wanted a comment saying that the default is enabled: true if content_types array is empty/nonexistent
