Allow control of the noCdn / no_cdn script parameters

[gguillen]

Description:
The default behavior of the install scripts is to contact aka.ms and then retrieve the installer from a subdomain of the azureedge.net CDN instead of going directly to subdomains of blob.core.windows.net. The underlying scripts already have parameters to control the behavior, it is just not exposed through the configuration of the action.

Justification:
Some users are behind strict firewall restrictions and it is hard to justify two additional domains instead of downloading the content from the already whitelisted blob.core.windows.net subdomains.

Are you willing to submit a PR?
Sadly, I cannot.

Hello @gguillen, Thank you for creating this feature request and we will get back to you once we have some feedback on this :)

Thank you again for raising this request. Since the dotnet install scripts have removed support for the --no-cdn flag as of dotnet/install-scripts#563, this functionality is no longer available to be exposed through setup-dotnet.
Please feel free to reach out if you have any further questions or would like additional clarification
