Change for running as a non-root user (#276)

* Enable running container as mqm * Fix merge problem * Don't force root usage * RHEL image runs as mqm instead of root * Build on host with SELinux enabled * Enable building on node in an OpenShift cluster * Enable running container as mqm * Fix merge problem * Don't force root usage * Merge lastest changes from master * RHEL image runs as mqm instead of root * Fix merge issues * Test changes for non-root * Make timeout properly, and more non-root test fixes * Run tests with fewer/no capabilities * Correct usage docs for non-root * Add security docs * Add temporary debug output * Remove debug code * Fixes for termination-log * Allow init container to run as root * Fixes for CentOS build * Fixes for RHEL build * Logging improvements * Fix Dockerfile RHEL/CentOS build * Fix bash error * Make all builds specify UID * Use redist client for Go SDK * Inspect image before running tests * New test for init container * Log container runtime in runmqdevserver * Add extra capabilities if using a RHEL image
