feat: add Obico for Klipper to KIAUH

[kennethjiang]

Hi @th33xitus, I think this PR is ready for review now. Sorry for the delay.

Here are a few areas that I will need your feedback on:

1. I have been naming the systemd service after the pattern of moonraker-obico[-xxx].service, which caused some problem with existing code. Since moonraker-obico has gone live for a while, I don't want to break the compatibility with the users already using it, I had to make changes here and here. The 2nd one is quite ugly. Let me know if you have a better idea.
2. moonraker-obico can be in an installed but *not linked" status. I made the change here and here. Again this is a bit of inverted dependency because now main_menu.sh and install_menu.sh depend on functions in obico.sh. Will love to hear your feedback here too.

Hi @kennethjiang, on first glance it looks like its going into the right direction. I saw one or two oddities, but as you stated that this is a rough draft, i'll wait until you give the go for me to start the formal review.

For example:

• i don't think that we need a python 3 check, as obico requires moonraker and moonraker requires python 3.
• also im not a fan of using the .* wildcard in the regex here: https://github.com/th33xitus/kiauh/pull/227/files#diff-08e65de842c3dbbcc98be9e5467e5447241080fbb0bcb661f162d58df16e6a60R20
• this is probably just kind of a copy & paste "placeholder"? https://github.com/th33xitus/kiauh/pull/227/files#diff-08e65de842c3dbbcc98be9e5467e5447241080fbb0bcb661f162d58df16e6a60R242

@th33xitus I changed this PR based on our discussion and tested all the cases I can think of.

I found 1 bug: on the install_menu screen, if the user selects 1) [klipper], 2) [moonraker], and 9) [Obico for Klipper] without going back to the main screen, function get_multi_instance_names will return an empty string.

I did some debugging and found that .kiauh.ini is not updated until the user goes back to the main screen. However, I struggled to figure out where I did wrong. Will appreciate it if you can provide some guidance here.

Please also go over the code again, particularly commits 7837a78c4b6113e76dc883058118c0a21eef3410, 7837a78c4b6113e76dc883058118c0a21eef3410, and 8d284179d8a21f7ef6720d5c9388a27e7fce58c5

You didn't do any wrong. You actually pointed me to a maybe not so smart solution. https://github.com/th33xitus/kiauh/blob/master/scripts/ui/main_menu.sh#L85

The init_ini function is called whenever the main menu is loaded. https://github.com/th33xitus/kiauh/blob/master/scripts/utilities.sh#L125

And in there the multi instance names are then written to the ini https://github.com/th33xitus/kiauh/blob/master/scripts/utilities.sh#L189

Maybe it is smarter to factor fetch_webui_ports and fetch_multi_instance_names out of the init_ini function and place them both into the install_menu function right after install_ui. Both those fetch functions aquire data that is usually only used in installation functions, at least i can't think of any other usecases within the script right now.

@kennethjiang so i just pushed a commit addressing the bug you mentioned.

I have a view comments to make on other pieces of the code, i quite don't understand yet.
