Add a new template for .nycrc for TypeScript files

[ishantiw]

Description

Currently we are moving packages to TypeScript and for that we need to change babel plugin configuration to process .ts files.

We need to create a new template file for .nycrc file under /templates folder. We will symlink this file in the root of packages that are migrated to TypeScript.

Below is the configuration.

 {
	"exclude": ["test/**", "**/*.d.ts"],
	"extension": [".ts"]
}
