EAP CD templates unsuitable for Online

As the primary platform for the EAP CD is OpenShift Online, we should drop things from the templates that aren't suitable for Online:

1. drop non-persistent DB templates (as there is no reason for them, as PV are available on Online)
2. Drop all the keystore configurations and use Edge termination for the routes by default. Currently all the https templates use Passthrough, which cannot work on Online Starter (as one cannot use custom route and thus can never generate a valid certtificate for the openshift.com domain), and also arguably won't make sense on Pro (as the only case where you can generate a valid certificate for passthrough is if you use a custom domain, which is probably not a typical use case for a "quickstart" template)
3. Drop the eap-cd-tx-recovery-s2i.json , as it requires ReadWriteMany, which isn't available on online
