Proposed changes

This change removes --keep-baud which can result in an unexpected baud rate for serial terminals.

When a specific baud rate speed is defined, or it is falling back to the VyOS default value of 115200. --keep-baud can result in the config value not being honoured.

If the terminal was created with a baud rate other than the config defined value, the config value will not be applied.

How to test

Tested on a Supermicro SOL serial port mapped to /dev/ttyS1. BIOS/IPMI is set to 115200.

stty -aF /dev/ttyS1 default output:
speed 9600 baud; rows 24; columns 80; ...

After set system console device ttyS1 speed 115200:
speed 9600 baud; rows 24; columns 80; ...

Removing --keep-baud:
speed 115200 baud; rows 24; columns 80; ...
