New Resource: azurerm_container_group

[tombuildsstuff]

Re-opening PR #311 by @abhijeetgaiha - which I accidentally closed by force-pushing :(

Original description:

---

This has a basic implementation for #287 .

The following features are TBD:

• Command lines
• Volume Mounts
• Environment Variables
• Private container registries

As mentioned on Slack - I just quickly skimmed over it (and it looks good overall) as I'm assuming you did more thorough review in the linked PR.
