we should really use Pathname#absolute? but it‘s not in all the ruby versions we support and it comes down to roughly this

Returns an aligned_string of text relative to the size of the terminal window. If a line in the string exceeds the width of the terminal window the line will be chopped off at the whitespace chacter closest to the end of the line and prepended to the next line, keeping all indentation.

The terminal size is detected by default, but custom line widths can passed. All strings will also be left aligned with 5 whitespace characters by default.

If the passed name starts with a / it‘s assumed to be regex and will use regex to match

Wrapper around PluginManager.loadclass

Parse a fact filter string like foo=bar into the tuple hash thats needed

Returns the current ruby version as per RUBY_VERSION, mostly doing this here to aid testing

On windows ^c can‘t interrupt the VM if its blocking on IO, so this sets up a dummy thread that sleeps and this will have the end result of being interruptable at least once a second. This is a common pattern found in Rails etc

Escapes a string so it‘s safe to use in system() or backticks

Taken from Shellwords#shellescape since it‘s only in a few ruby versions
