Variable-Mapper action maps variables by regular expressions.
- The map argument is a configuration in json format.
- The top-level key in JSON is a regular expression condition. They are evaluated in order from the top.
- The value is the key-value pair of variables to be exported.
- The key argument is the key to match the map.

The mode option can be used to change the behavior of getting variables.
first_match, overwrite and fill are valid values.
first_match evaluates the regular expression of a key in order from the top and gets the variable for the first key to be matched.

overwrite evaluates the regular expression of the keys in order from the top, and then merges the variables associated with the matched keys in turn. If the same variable is defined, the later evaluated value is overwritten.

fill evaluates the regular expression of the keys in order from the top, and then merges the variables associated with the matched keys in turn. If the same variable is defined, later evaluated values are ignored and the first evaluated value takes precedence.
