[Shared library] Global variables in parallel

[Maciej Gąsiorowski]

Hi, 

I have shared library with global variables as stages (https://jenkins.io/doc/book/pipeline/shared-libraries/#defining-a-more-structured-dsl):

+ src
+ vars
  - stage1.groovy
  - stage2.groovy
  - stage3.groovy

I is possible to create library to run them in parallel, something like this (or something similiar) - Jenkinsfile:

parallelStages {
  stage1 {
    argument = "test1"
  }
  stage2 {
    argument = "test2"
  }
  stage3 {
    argument = "test3"
  }
}

Or is there anothey way to agregate such stages and execute them in parallel ?

I've tried different things but they do not work.

Regards,
Maciek
