[Discussion] Should ArmClient send parameterSetName & commandName headers to ARM?

The following two headers can be used to provide more information about the source of an HTTP request in ARM's logs:
* `x-ms-command-name`
* `x-ms-parameter-set-name`

Might be worth setting these to help understand the source of a particular request (e.g. "Insert Resource", or "Deploy to Azure" etc)

Start by locating the ArmClient request path and verify how x-ms-command-name and x-ms-parameter-set-name are defined by Azure ARM. Determine whether values can be supplied for each request, then establish the scope and completion criteria for sending them; no files or tests are named in the issue.
