Changes to nuget functionality

[freddydk]

With this release the implementation for delivering to NuGet packages (by adding the NuGetContext secret), is similar to the functionality behind delivering to GitHub packages and the implementation is final.

New Settings:

• trustMicrosoftNuGetFeeds Unless this setting is set to false, AL-Go for GitHub will trust the NuGet feeds provided by Microsoft. The feeds provided by Microsoft contains all Microsoft apps, all Microsoft symbols and symbols for all AppSource apps.
• trustedNuGetFeeds - can be an array of NuGet feed specifications, which AL-Go for GitHub will use for dependency resolution. Every feed specification must include a url property and can optionally include a few other properties:
  • Url - The URL of the feed (examples: https://pkgs.dev.azure.com/myorg/apps/\_packaging/myrepo/nuget/v3/index.json or https://nuget.pkg.github.com/mygithuborg/index.json")
  • Patterns - AL-Go for Github will only trust packages, where the ID matches this pattern. Default is all packages (*).
  • FingerPrints - If specified, AL-Go for GitHub will only trust packages signed with one of the fingerprints specified in this array of fingerprints.
  • AuthTokenSecret - If the NuGet feed specified by URL is private, the authTokenSecret must be the name of a secret containing the authentication token with permissions to search and read packages from the NuGet feed

Looks good.

Left some comments, so one more iteration might be needed.
