[PROTOTYPE] [WIP] Regex for parsing taskoutput results

[LasmarKhalifa]

Regex-based parser prototype for taskoutput's tool result message.

This introduces a helper method that looks for any tag and returns its contents. It's regex-based, which means there are no issues related to unescaped characters. This also means it can be used for error_lines(as shown in this prototype).

The drawback is that in some cases, this can fail (cases such as <status>a</status>x</status>). However, we don't expect this to ever happen in our use cases.
