roles/graylog: Add Graylog server deployment

The *graylog* role installs Graylog from the *graylog2.org* Yum
repository and manages basic server configuration.  It augments the
default systemd unit to provide the `CAP_NET_BIND_SERVICE` capability to
the Graylog server process via ambient capabilities, thereby allowing
the server to bind to the privileged Syslog UDP port.
