Install packages using Choco

Is your feature request related to a problem? Please describe.
I would like to automate installation of packages through choco

Describe the solution you'd like
As a user, I should be able to:

• Install packages by providing a list of package names and version names:
• as a list as package@version, with version as optional (pick latest)
• For each package, I should be able to specify: additionalOptions that are passed through to choco

other requirements:

• accept all licenses (yes to all) by default
• install choco if not present

For v1, we will NOT support using a config file.
we can print out that by using this task, you are accepting licenses
we will only support additional options.

setupTasks:
 - task: choco
    inputs:
      package: "packageName@version"
      additionalOptions: "--key val"
