Support external application project integrations

[BoxBoxJason]

What problem are you facing?

It is currently not possible to create / configure (external) application integrations using the crossplane provider.
I would love to have them reconciled to not worry about my users changing the settings

I'd like to be able to set them using my kubernetes CRD.

How could Crossplane help solve your problem?

Could add CRDs similar to terraform:

• Custom issue tracker
• Emails on push Add Emails-on-push integration #278
• External Wiki
• GitHub Support Github integration #289
• Harbor
• Jenkins
• Jira
• Mattermost Management Policies and/or Init Provider Support provider-argocd#268
• Microsoft Teams
• Pipelines email Implement Pipeline Status Emails #288
• Redmine
• Telegram
• Youtrack
