httpd/db artifacts broken
@tebeka the artifacts get/store etc is broken 

a. you must use the `artifact.to_json()` vs dumps like in filedb, since `to_json()` accounts for model details, also `body` is not stored in the DB

b. artifacts object path should be `/artifact/<project>/<uid/tag>/<key>'  (key not as arg)
, (uid/tag is like a git tree and can also list all keys in a tree)
