…allel (#7075)

* Make sure to run parallel commands part of a composite command in parallel

* Display warnings in case there are errors when executing pre-stop events

* Fix the command_composite_parallel.go implementation by lowering the case of the sub-command names

Since this passed the Devfile validation logic, we should use the same logic as in command_composite.go
