Documentation for templates

[BernieWhite]

Build out documentation for additional metadata that can be added to template. For example:

PSDocs.Azure/templates/storage/v1/template.json

Lines 4 to 7 in 6004255

	"metadata": {
	"name": "Storage Account",
	"description": "Create or update a Storage Account."
	},

PSDocs.Azure/templates/storage/v1/template.json

Lines 18 to 22 in 6004255

	"metadata": {
	"description": "Optional. The Azure region to deploy to.",
	"example": "EastUS",
	"ignore": true
	}

Documentation needs to be published under MicrosoftDocs.
