Add MaxNodes to Native config (#3427)

* Add MaxNodes to Native

* It compiles...

* Convert nodedb to use new

* Closer but still broken.

* Finally working

* Remove unintended lines

* Don't include a pointer

* Capitalization matters.

* avoid rename in protocol regen

* When trimming the nodeDB, start with a cleanup

* Remove extra cleanupMeshDB() call for now
