HDDS-15367. Shell completion knows too few commands

[adoroszlai]

What changes were proposed in this pull request?

Shell completion, implemented in HDDS-12811, knows about only very few commands:

$ ozone completion bash | grep 'local cmds'
  local cmds0=(genconf)
  local cmds1=(getconf)
  local cmds2=(completion)
  local cmds3=(ratis)
  local cmds4=(getconf confKey)
  local cmds5=(getconf -confKey)
  local cmds6=(getconf storagecontainermanagers)
  local cmds7=(getconf -storagecontainermanagers)
  local cmds8=(getconf ozonemanagers)
  local cmds9=(getconf -ozonemanagers)
  local cmds10=(completion bash)
  local cmds11=(completion zsh)

It was broken by HDDS-14595, which removed ozone-cli-shell etc. from classpath of ozone-tools.

This PR changes ozone completion to run in ozone-dist, the module which depends on all other Ozone modules. This makes all ozone subcommands available on the classpath.

How was this patch tested?

$ ozone completion bash | grep 'local cmds' | wc -l
344

Also tested completion after:

$ source <(ozone completion bash)
$ ozone <TAB><TAB>
admin       completion  debug       freon       genconf     getconf     ratis       repair      s3          sh          tenant      vapor       
$ ozone debug <TAB><TAB>
auditparser  checknative  datanode     kerberos     ldb          log          om           ratis        replicas     version
