Azure-functions-core-tools: [V2] remove dependency on ./dotnet from the CLI

[ahmelsayed]

The only scenario that requires dotnet executable to be on the machine is that of installing extensions because we just launch dotnet add extensions.csproj package <extension> --version <version>

this is the only command that would prevent building a self-contained cli

Any ETA on when this dependency can be removed?

Running azure functions via node container and need to install extensions so I ran into this.

closing as resolved by extension bundles
