Don't send generic "command" events

[fbricon]

after discussing with @sonyccd, we should stop sending generic "command" events with an identifier property.

vscode-openshift-tools/src/telemetry.ts

Line 64 in d6f7b8e

sendTelemetry('command', eventProps);

and use the commandId

vscode-openshift-tools/src/telemetry.ts

Line 61 in d6f7b8e

identifier: this.commandId,

This'll make it easier to analyze behavior patterns on the backend

@fbricon I have no problem to remove it, would you explain in what way sending 'identifier' makes things harder and not sending it makes it easier?
Another question, what 'backend' specifically are you talking about?
