Description

Currently, when one of the Dockerfiles (located at https://github.com/apache/hadoop/tree/trunk/dev-support/docker) changes, all the platform builds are run.
For example, a change to Dockerfile_debian_10 would trigger a run for Centos 7, which isn't relevant.
This leads to unnecessary delays in PR validation. We should thus limit the changes specific to the platform for the case where the corresponding Dockerfile changes.
