[JENKINS-71247] Support labels without associated resources

Currently, you need at least one resource for a label.

When I try to lock on a label and no resource exists (yet) for that label, pipeline fails with

java.lang.IllegalArgumentException: The resource label does not exist: my_label.

at org.jenkins.plugins.lockableresources.LockStep.validate(LockStep.java:183)

at org.jenkins.plugins.lockableresources.LockStepExecution.start(LockStepExecution.java:43)

use case:

I want to create a pool of resources (testsystems btw) to be used in a build pipeline. The resources are created on-demand by a separated groovy-script job.

During nighttimes the pool will be completely empty though, and the build pipeline will so fail hard instead of waiting for the next resource
