Upgrades: record google analytics events for google-voucher.

[retrofox]

Issue: #5978

Records events when the user does the google voucher flow.

Testing

Set debug with calypso:analytics.

localStorage.setItem('debug', 'calypso:analytics');

Make the google voucher flow and take a look to the console. You should see how the events are recorded:

Nice, working for me.

The code also looks fine.

Edit: I just noticed that one of the event names is not right — the last one. It should be ``calypso_plans_google_voucher_setup_clickbut it iscalypso_plans_google_voucher_setup_clic` instead.

Why it needs to be debounced? To prevent accidental double-clicks of the button?

[retrofox]

Right.

Thanks @lamosty
