add tools/commands checking in artifact-test

[amoskong]

We currently catch some packaging issue of debian9/ubuntu in upgrade test, that's too late.
Artifact-test is a good chance to test it quickly. We don't need to cover all subcommands, just check if commands/tools are installed, and java class files are installed correctly.

• Check items
  • make sure the command exist
  • No error of Could not find or load main class com.xxxx
  • $cmd --help works, check return value

• nodetools

  • status
  • describering
  • flush
  • snapshot
  • etc

• cassandra-stress

  • ..

• cqlsh

• cassandra-stressd

• scylla-sstableloader?

• sstableloader

• sstabledump

• sstableupgrade

• local_file_key_generator

• configuration_encryptor

• ...

@roy @slivne any suggestion?

Looks like a good idea to me.
Every tool that we have should be listed somewhere so we can trigger it automatically from that list.
