Remove azure pipelines

[ryandesign (Ryan Carsten Schmidt)]

Per Azure:

The macOS-10.14 environment is deprecated and will be removed on December 10, 2021. For more details see ​https://devblogs.microsoft.com/devops/hosted-pipelines-image-deprecation/

We use GitHub Actions for macOS 10.15 and later, so we no longer have any need for Azure Pipelines and everything related to it can be deleted from MacPorts.

GitHub organization admins should remove Azure Pipelines integration and revoke all permissions related to it.

If you can tell me were to go and what to click I'll do it...

Please check out these pages:

1. ​https://github.com/organizations/macports/settings/installations
2. ​https://github.com/organizations/macports/settings/oauth_application_policy

We should also remove Travis CI if it exists.

Thanks. There are too many settings screens to know where anything is anymore!

At (1) both Azure Pipelines and Travis CI were listed as installed GitHub apps. I suspended both of them. Before completely uninstalling them I see that Travis CI was listed as having access to macports/upt-macports and Azure Pipelines had access to that and macports/buildbot-macports-custom-views so we should figure out whether those still need that access or no.

I see these CI configuration files for those projects:

• ​https://github.com/macports/buildbot-macports-custom-views/blob/master/.travis.yml
• ​https://github.com/macports/upt-macports/blob/master/.travis.yml
• ​https://github.com/macports/upt-macports/blob/master/azure-pipelines.yml

At (2) Travis CI and Travis CI for Open Source were still listed but already denied, and Azure Pipelines (OAuth) was listed as approved; I changed it to denied. I assume that since Travis was already denied here, the .travis.yml files above can't have been used for anything anymore and could be removed, but I don't know about the azure-pipelines.yml file.
