Add application to configure rsyslog
The application implements the xyz.openbmc_project.Network.Client D-Bus
interface to set a remote rsyslog server's address and port in the
rsyslog config file.
This lets us configure rsyslog to be able to stream out logs.
TODO: Exception handling and validation will be handled in subsequent
commits.
