Workbench's Maven Repository is not "cluster-aware"

Description of problem:

Various operations within the business-central publish JARs to business-central's internal Maven Repository (e.g. "Upload artifact", "Build&Deploy project").

Furthermore following completion of https://bugzilla.redhat.com/show_bug.cgi?id=1112062 "mvn deploy" of Maven projects to business-central's Maven Repository (that have been correctly configured to include the remote repository in their <distributionManagement> pom.xml settings).

This is all well and good, however these operations write to the underlying file-system which is not, by default, "cluster-aware". This is not a problem when business-central is not deployed in a cluster however when it is the aforementioned operations will lead to sporadic results on nodes within the cluster.

Version-Release number of selected component (if applicable):

6.0.2.

Steps to Reproduce:
1. Set-up a business-central cluster
2. Create an external Maven project (see the referenced BZ)
3. mvn deploy

Actual results:

Only the node in the cluster directly referenced in the project's pom's <distributionManagement> section will have the deployed JAR. At worse, if the pom was configured to point to a load-balancer the node on which the JAR is deployed will be inconsistent.

Expected results:

Nodes in a cluster are synchronized.
