Summary

This adds CEL-based mutations to the syncagent. CEl is nice because it allows for simply arithmetic and logic operations without the possibility to too much danger.

The implementation is quite simple: You configure a tuple of (path,expression) and then the agent will find the value at the given JSONPath in an object, process it using the CEL expression and then writes the resulting value back into the object. THe selected value and both full objects are available as variables in the expression.
