Extract Nuget downloading features from PluginFramework to a separate project

PluginFramework contains a feature which allows to use Nuget-packages as plugins. The code is available from here: https://github.com/weikio/PluginFramework/tree/master/src/Weikio.PluginFramework.Catalogs.NuGet

Changes

Move the PackageManagement code from PluginFramework into this separate repository. Project name and namespace should be Weikio.NugetDownloader.

Publish the Weikio.NugetDownloader as a separate Nuget-package.

Change PluginFramework so that uses the new Weikio.NugetDownloader package.

Support for downloading the latest version from a specific "ring"

It should be possible to download the latest "stable", "alpha", "beta", "rc" etc. version easily.

Download(packageName) should default to the latest stable.
Download(packageName, "beta") should download the latest beta.

Though in some cases it should be possible to define the "ring" and also the major. So maybe something like:

Download(packageName, "3..beta")

Not sure about the syntax. Any ideas?

When your plugin has a Windows specific TFM the nuget catalogs don't work

If you have a nuget based plugin that uses a TFM like "net6.0-windows10.0.19041" the nuget catalog initializations will fail even if the executable loading the plugins is targeting the same TFM. This is due to a difference in how the NuGetFramework parse calls behave. When these calls are made within the nuget downloader they return framework objects that don't pass the test:

            var _compProvider = new CompatibilityProvider(new DefaultFrameworkNameProvider());
            var compatible = _compProvider.IsCompatible(bal, baz);

NuGetFramework.Parse("net6.0-windows10.0.19041")
NuGetFramework.ParseFrameworkName("net6.0-windows10.0.19041", frameworkNameProvider);

Line 133 in 146d2e9

var nuGetFramework = NuGetFramework.ParseFrameworkName(targetFramework, frameworkNameProvider);

Only get required dependencies

Currently too many packages are downloaded based on the dependencies. For example runtime.native.System.Security.Cryptography.Apple.4.3.0, runtime.ubuntu.14.04-x64.runtime.native.System.Security.Cryptography.OpenSsl.4.3.0 etc.

Here's some good ideas of how to get only the necessary packages: https://alistairevans.co.uk/2020/04/17/loading-plugins-extensions-at-run-time-from-nuget-in-net-core-part-1-nuget/

Support for downloading specific version

It should be possible (and easy) to download a specific version of Nuget package. The syntax should be something like:

Download("packagename", "packageversion").

It shouldn't matter if the packageversion is prerelease or not.
