add starttls property to java_certificate resource

Description

This adds the ability to fetch a TLS certificate from an endpoint that speaks a dialect of TLS other than HTTPS.

Some refactoring of the tests suites is included because it seems that the java_certificate resource was not being tested in many cases. Also, the adoptopenjdk* fixture recipes were simplified to a single recipe using attributes.
