Quarkus: Support QueryDSL in Panache

[hantsy]

QueryDSL is very popular in developer communities, as an alternative of JPA APIs, it is better to add it in Quarkus.

Optional predicates #2303 and type safe HQL might be a good replacement for QueryDSL. We looked at QueryDSL but it does not seem to be maintained anymore, that's why we hesitated to invest in it. If you can be a bit patient, let's see if the solution ^ solves your problems. Or you can try and contribute QueryDSL to Quarkus.

As this post suggests QueryDSL is again maintained by a small team separate from the previous owner, however, the assumption that they would succeed is fragile.

Personally, my benefit from Querydsl was build-time query checking and IDE code completion. I used it as a plugin for Spring Data (example here https://www.logicbig.com/tutorials/spring-framework/spring-data/query-dsl-basic.html), and it was awesome. But Querydsl is not a must have, If some other instrument will give me the same benefits and will be easy to use, I will deffinitely go for it.

Also, type-safe querries in Quarkus could be a good move in competition with Micronaut, since IMHO for now, they have better storage integration options.
