hey binary package in Ubuntu Oracular amd64

 HTTP load generator, ApacheBench (ab) replacement, formerly
 known as rakyll/boom
 .
 Originally called boom and was influenced from Tarek Ziade's
 tool at github.com/tarekziade/boom. Using the same name was a
 mistake as it resulted in cases where binary name conflicts
 created confusion.
 .
 To preserve the name for its original owner, this project
 was renamed to hey.
