Support "wildcard" versioning

NodeJS seems to use semantic versioning.  This would mean that using a form of "wildcard" in specifying a version number might be useful.  This might also be useful in tracking latest LTS releases.

Examples:
-  8.x -> latest minor release after 8.0 major release
-  10.14.x -> latest patch release after 10.14 minor release
-  lts/* -> latest release marked as LTS
