Woo Installer: plugin install and activate

[lsl]

The woocommerce-installer's transfer step needs to make use of our new api endpoints (12-gh-Automattic/woo-on-plans) to ensure woo + wc pay is installed and active.

The transfer step should:

• Check if woo + wc pay is installed
• Install them if they are not
• Activate them if they are not

To implement this it's expected we'll replace our current usage of initiate-transfer with the new endpoint that can "repair" site state with atomic transfer and or install plugins as needed. The new endpoint will need to be polled until it returns a success status.
