Subject: [PATCH] Use a shallow git clone on Jenkins when possible for main
 build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

there are currently issues with disk space available on the Jenkins
nodes.
Camel is one of the most consuming one. Each of its workspace for Camel
core is taking 4.4G, it includes 1.4G for the .git folder.
Using a shallow clone should reduce the 1.4G to 63M and gain few minutes
to the build too.
