Add support for self_hosted_domains in access apps

[GreenStage]

buils failing as this depends on cloudflare/cloudflare-go#1281

[github-actions]

This project handles dependency version bumps (including upstream changes from cloudflare-go) independently of the standard PR process using automation. This allows the dependency upgrades to land without causing merge conflicts in multiple branches and handled in a consistent way. The exception to this is security related dependency upgrades but they should be co-ordinated with the maintainer team privately.

Please remove the changes to the go.mod or go.sum files from this PR in order to proceed with review and merging.

i don't think we needed to remove these 🤔

[jacobbednarz]

@GreenStage you'll need to rebase this a little to get this into a working state (a good example why we leave dep bumps outside of these PRs).

[GreenStage]

@jacobbednarz done!

[jacobbednarz]

acceptance tests are passing but we will confirm a couple of points before we merge about the internal service handling.
