Geo-rep: Adding regression tests for geo-rep

This patch introduces upstream regression suit for geo-replication

    * Modifies cleanup (tests/include.rc) to remove everything but
      hook-scripts.

Prerequisites:
    * Passwordless SSH from root to root of current host.
    * Export /build/install/sbin and /build/install/bin to PATH
      variable for root user.
