Fixes #38025 - Add label option when creating organization

[adamlazik1]

What are the changes introduced in this pull request?

When creating new organization in the UI, the user has the option to input a custom organization label.

Considerations taken when implementing this change?

The label field was removed probably accidentally in #10880.
This action is still doable in API so it should be doable in UI as well.

What are the testing steps for this pull request?

1. In the web UI, navigate to Administer > Organizations.
2. Click New Organization.
3. Input Name and custom Label and submit.
4. Verify that the inputted label is present by clicking on the organization and displaying its details.

Looks good, the field is there, label gets derived from the name if the field is left blank, if the label is given explicitly it gets saved.

On the other hand, if you give a value and that value is invalid (contains spaces for example), it shows bad URI(is not URI?): "https://localhost:23443/candlepin/owners/something else" error instead of a proper validation error. I'd be willing to treat that as a separate issue

ACK, code looks fine and works correctly:

I agree with Adam about the validation error, do you mind filing a redmine issue @adamlazik1
