Enable odo telemetry based on current vscode telemetry opt-in status

[dgolovin]

If current user consents to send telemetry, odo telemetry should be also enabled using environment variable ODO_TRACKING_CONSENT to yes . TELEMETRY_CALLER should be set to vscode to send IDE name with telemetry event.

If env var VSCODE_REDHAT_TELEMETRY_DEBUG set to true, ODO_TRACKING_CONSENT should be set to no no matter if telemetry is enabled or not to avoid telemetry reporting during development.
