Add irule via tmsh without deleting existing irules, and how to re-order

There was a similar question a couple of weeks ago, asking about adding and deleting individual profiles. I am using 11.4.1, and found that the equivalent syntax for the rules collection within a virtual does not work. I think you are stuck with rewriting the entire rules list.

This may not apply to other versions. I know through various versions little things like this are broken and fixed in tmsh. Things like being able to use wildcards for some objects and not others. The code behind tmsh must be dreadful.
