Clone repo

Is your feature request related to a problem? Please describe.
I would like to clone a repo I have access to

Describe the solution you'd like
parameters to support:

1. src repo url
2. clone to directory
3. params to pass to git clone

Support for repo sources:

1. github
2. ADO

pre-requisites:
If git and GCM (>= GCM 2.1..2,) are not installed, install them first. We should check if PATH already contains git and GCM. If yes, but older versions: overwrite with supported git and gcm version.

setupTasks:
  - task: clone-repository-on-login
    inputs:
      src: "repo-url"
      cloneTo: "./path/"
      additionalOptions: "--flag --key val"

A few design questions:

• How will we ensure that Git & Git Credential Manager are on the box?
• What min-versions of Git & GCM do we want to require? The latest release, GCM 2.1..2, specifically includes some new functionality that will improve Azure Repos OAuth connectivity (Use OAuth tokens on DevBox by default for Azure Repos git-ecosystem/git-credential-manager#1245)
• I understand that this version of this task will run upon first user login so that we can prompt for OAuth - should we make that explicit in the name like "clone-repository-on-login"?

Jordan and I discussed this... considering we're going to be in private preview, we can name the task clone-repository-on-login and be more explicit and set expectations that this would run after login, unlike all the other tasks that we provide. We could deprecate it later once we have a way to clone repositories at provision time using secrets. I updated to comment to reflec this, and GCM dependencies
