[angelozerr]

This PR fix #430

The OSUtils was renamed to Platform which is more generic (eclipse like
name) which contains information about OS, JVM (name, version, memory).

@fbricon I have add telemetry to track explicit action from user, that's to say:

• rename
• formatting
• rangeFormatting

In vscode trace, you should see :

[Trace - 09:44:17] Received notification 'telemetry/event'.
Params: "textDocument/formatting"

if you format a XML file.

Looks OK, but please add some unit tests before we merge it.

It will hard to do that since it depends on OS where JUnit are executed (I think about JVM and OS information).

Or perhaps you wish I write test just with rename, formatting, rangeFormatting, and onInitialized but by avoiding value check of OS, JVM memories?

An another question, I tell me if we should give the capability to send telemetry or not. Here some ideas:

• add settings to disable telemetry?
• add client capability 'telemetry' to enable telemetry. For instance I think LSP4E will never used those telemetry events.

You can check telemetry data contain the same values as what's in Platform, and then check memory values are > 0.

Yes an xml.telemetry.enabled preference would be useful.
