Run console on the serial port if required

This commit adds the ability to use IPMI SOL console when the nodes
provisioned with an option 'console=ttySx' or 'console=ttySx,speed',
where x is 0 for the COM1 and 1 for COM2. If speed parameter doesn't
provided so 9600 used as default. This feature can be used for the
bootstrap nodes too.
