Add Option "check_storage" and "check_container_ressources"

[MickLesk]

Description

1. added new function:
check_storage
=> This message already appears in some LXCs and has now been adopted as a basic function in build.func.

This can be added in the function update_script() area. (ct/lxc.sh).
It should be added subsequently for all CTs.

---

2. added new function:
check_container_ressources
=> if the ressources are not enough based on ct/script.sh the script exit with an output.
=> This message only appears if the RAM < var_ram or the cores < var_cpu of the CT

This can be added in the function update_script() area. (ct/lxc.sh).
It should be added subsequently for all CTs.

3. GENERAL:
The ct\lxc.sh scripts should now always look like this in the update area (keyword: harmonization)

function update_script() {
header_info
check_container_storage
check_container_resources

And yes, I think the icons are better than the Ascii X and Check-Mark characters. 😄

Every terminal/console has supported them for several years. I will also bring it up to date in the next merges (the rest).

Good idea and nice utility functions, will make scripts much cleaner
