For long-running tasks where we have some output from the task that gives us some idea of the progress of the task (such as a percentage complete), provide the means to scrape the output for that progress information and show it to the user in the default knotty terminal output in the form of a progress bar. This is implemented using a new TaskProgress event as well as some code we can insert to do output scanning/filtering. Any task can fire TaskProgress events; however, if you have a shell task whose output you wish to scan for progress information, you just need to set the "progress" varflag on the task. This can be set to: * "percent" to just look for a number followed by a % sign * "percent:<regex>" to specify your own regex matching a percentage value (must have a single group which matches the percentage number) * "outof:<regex>" to look for the specified regex matching x out of y items completed (must have two groups - first group needs to be x, second y). We can potentially extend this in future but this should be a good start. Part of the implementation for [YOCTO #5383].
