Allow profiling using Intellij

[eddumelendez]

Currently, Intellij provides profiling CPU Profiler, Allocation Profiler and Java Flight Recorder but when those are selected for a test or -main the following log is displayed.

I was also just learning about IntelliJ profiling and I got this error, when I tried to start a Local Clojure REPL run config with the Profile with 'IntelliJ Profiler' option, instead of the default Run option:

Deferred configurations cannot be run with standard runners

I would be really curious to know how are we supposed to run this built-in profiler.

BTW, here are some really useful links for learning about profiling:

• https://www.baeldung.com/java-profilers
• A Simple Approach to the Advanced JVM Profiling

Just tried https://github.com/clojure-goes-fast/clj-async-profiler and I could use it for CPU profiling, but it's not integrated with IntelliJ, of course.

To anyone looking at this, you just need to use "Attach profiler to process"
