SpringJPA: Support spring.jpa.show-sql

[snowdrop-bot]

Description
From a Hackaton with Quarkus suggestions and feedbacks:
User tried to set spring.jpa.show-sql was surprised it didn’t work.

Implementation ideas
My idea is create a @ConfigRoot and @ConfigGroup classes to load this property and map it to the current quarkus.hibernate-orm.log.sql. Anyway the new spring property would be named quarkus.spring.jpa.show-sql, we cannot escape to have quarkus in the name. WDYT @geoand ?
