Initial implementation

Testing

This requires creating a Virtual machine scale set on Azure and pointing the below config at it.

Config

concurrent = 4

[[runners]]
  name = "azure runner"     
  url = "https://gitlab.com"
  token = "<snip>"

  [runners.autoscaler]
    capacity_per_instance = 1
    max_use_count = 1
    max_instances = 5
    plugin = "fleeting-plugin-azure"

    [[runners.autoscaler.policy]]
      idle_count = 0
      idle_time  = "20m"
