* Created op-mode command "restart serial console"
* Relocated service control to vyos.utils.serial helpers, used by conf- and
op-mode serial console handling
* Checking for logged-in serial sessions that may be affected by getty reconfig
* Warning the user when changes are committed and serial sessions are active,
otherwise restart services as normal. No prompts issued during commit,
all config gen/commit steps still occur except for the service restarts
(everything remains consistent)
* To apply committed changes, user will need to run "restart serial console"
to complete the process or reboot the whole router
* Added additional flags and target filtering for generic use of helpers.

Add util function to set serial console speed in accordance with revised
GRUB file structure; in keeping with the intentions of the config_mode
script, adjust the GRUB var 'console_speed' to only modify ttyS0.

Only start console if it exists on the running system. If a user detaches a
USB serial console and reboots - it should not fail!

During testing it was discovered that there is a well known problem (we had for
ethernet interfaces) also in the serial port world. They will be enumerated and
mapped to /dev/ttyUSBxxx differently from boot to boot. This is especially
painful on my development APU4 board which also has a Sierra Wireless MC7710
LTE module installed.
The serial port will toggle between ttyUSB2 and ttyUSB5 depending on the
amount of serial port extenders attached (FT4232H).
The shipped udev rule (/usr/lib/udev/rules.d/60-serial.rules) partly solves
this by enumerating the devices into /dev/serial/by-id folder with their name
and serial number - it's a very good idea but I've found that not all of the
FT4232H dongles have a serial number programmed - this leads to the situation
that when you plug in two cables with both having serial number 0 - only one
device symlink will appear - the previous one is always overwritten by the
latter one.
Derive /usr/lib/udev/rules.d/60-serial.rules and create a /dev/serial/by-bus
directory and group devices by attached USB root port.
