Ability to remove Gitlab Pages default URL if custom URL added.

Problem to solve

After adding custom domain under GitLab Pages, allow the default URL (username.gitlab.io) to be removed.

Avoids links to incorrect URL, or Google/web searches to Gitlab.io URL rather than custom domain.

Proposal

Allow default username.gitlab.io URL to be deleted (if custom domain is connected)
