Add rules for Vert.X

# Task Description

We would like to see specialized rules for the [Vert.x](https://vertx.io/) Java framework. This is a popular Eclipse framework [hosted on Github](https://github.com/vert-x3/) with over 13000 followers (as of now).

Based on our research, it appears Checkmarx is the only SAST tool that has rules for Vert.X, targetting Kotlin.

Our codebase is written in Java and heavily dependent on Vert.X. We are already using GHAS for scanning our private repositories (in GHES). We would like to not need to use several different tools such as Fortify, Checkmarx, Mend, etc for the job.

It would be great, it we could see the same support in CodeQL.

# Task List

* [ ] Collect a list of common security issues in Vert.X

* [ ] Update the documentation
