Mutants/add skip attribute to timeout functions

[ASuciuX]

Why are mutations causing timeouts?

Mutations cause timeouts because mutants modify the return value of functions. If the function is essential for stopping a loop or waiting for an HTTP response, when it returns something else, it either doesn't stop waiting for the code or creates an infinite loop, leading to a timeout.

Attributes to skip mutants on functions that timeout. Packages covered:

• [x] stacks-node
• [x] stackslib
