Parameter templating for ARM templates

This extension enables you to inject parameters into exsisting ARM templates. This solves the problem where you have duplicated required parameters spread over the templates.

To use this the extension propperly you need to create a new JSON file with the parameters section in it. After that, move all the parameters that need to be injected to that file.

In the pipeline you add this task as the first step in the pipeline as it modifies the files (only during the build).

Note: this does not affect any files stored on the repo.

In the future I will make a Visual Studio extension to fix the false-positives that the parameters do not exsists and link it somehow.
