Create simple URI friendly search language which will be linked to Panache criteria queries

[sberyozkin]

Description
This feature request has been inspired by reading #2303.
A number of high profile languages exist such as OData, GraphQL. However something simple such as FIQL which does not require URI encoding and is easy to use to create the queries may be used as is or as an idea for creating a Quarkus own language.
A combination of this language plus Panache can let users write generic DB browsers on top of Quarkus.

Implementation ideas
Parser should be able to produce a typed Panache friendly expression, possibly with the help of the Panache visitor.
