Subject: [PATCH] Disable concurrent builds to reduce memory usage

As described in the issue #1343 builds get killed by the OOM killer
sometimes.

Add lock('iis-build') to the build options to reduce
memory usage whem multiple builds are triggered.
As described eg. in https://issues.jenkins.io/browse/JENKINS-35359
the disableConcurrentBuilds option can only prevent concurrent builds
of a single branch and using locks is the recommended workaround
for serializing all the builds in a multibranch pipeline.
