Initial support for generating a configuration file from machine configuration

Summary of the pull request

Initial support for generating a configuration file from the machine configuration flow.

Limitation in this PR:

• Exporting Dev Drive DSC task is not available in this PR.
  • Relevant PR: VirtualHardDisk: Resource for creating and attaching a virtual disk dsccommunity/StorageDsc#279
• Exporting repositories uses git. (we should figure out a way to distinguish which version control tech is used, maybe include this info in the SDK?)
