Update Maven to 3.5.3

Release notes: https://maven.apache.org/docs/3.5.3/release-notes.html

We need to upgrade our Maven build tooling to Maven 3.5.3. From the mailing list discussion (https://lists.opendaylight.org/pipermail/release/2018-April/014799.html) we discovered that the off by 1 timestamp issues that hit us last release is back and hurting us with distribution check jobs... Maven 3.5.2 was patched to solve the timestamp issues so it's about time we started updating our build tooling to use it.

We were hit by this before during the Nitrogen release and caused us to revert our maven-merge jobs from global-jjb back to ODL merge jobs and at the time it affected our merge jobs. It appears that our distribution-check jobs are now hitting the same issue. This time distribution-check is not a new job nor has it changed in awhile so there's nothing to revert to. It is time we upgraded our Maven builder to 3.5.3.
