METRON-831: Add lambda expressions and rudimentary functional programming
primitives to Stellar
## Contributor Comments
To enable use-cases where the user may want to do simple iteration, we can
expose simple functional primitives such as:
* `MAP`
* `REDUCE`
* `FILTER`
To fully support this, we will need lambda expressions as arguments to
these functions.
I also added a simple `LIST_ADD` to enable better testing of the functions
and because it was an easy-to-fill gap.
