SSH show-queue: option to group output by queue and print queue info

When the new option --by-queue is used the output of the show-queue
command is grouped by the work queue. Queue name is printed on top of
the tasks list and the number of worker threads assigned to that thread
pool is printed in the summary line. This option should help Gerrit admins
to identify which thread pools need to be adjusted.

For comparison, here is an example output without the new --by-queue option:

  Task     State        StartTime         Command
  ------------------------------------------------------------------------------
  9d51b721              16:29:14.750      git-upload-pack '/gerrit' (admin)
  18fr4561              16:29:14.750      git-upload-pack '/gerrit' (admin)
  ad52b823              16:29:14.750      git-upload-pack '/gerrit' (admin)
  bd51bbcc              16:29:14.750      git-upload-pack '/gerrit' (admin)
  11223344              16:29:14.750      git-upload-pack '/gerrit' (admin)
  3d120b5c 17:28:20.169 16:28:20.169      Log File Compressor
  ------------------------------------------------------------------------------
    6 tasks

With the --by-queue option the output looks like:

  $ ssh -p29418 admin@localhost gerrit show-queue -w --by-queue
  Task     State        StartTime         Command
  ------------------------------------------------------------------------------

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Objective

Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.

Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.

Documentation

For information about how to install and use Gerrit, refer to the documentation.

Source

Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.

Reporting bugs

Please report bugs on the issue tracker.

Contribute

Gerrit is the work of hundreds of contributors. We appreciate your help!

Please read the contribution guidelines.

Note that we do not accept Pull Requests via the Github mirror.

Getting in contact

The IRC channel on freenode is #gerrit. An archive is available at: echelog.com.

The Developer Mailing list is repo-discuss on Google Groups.

License

Gerrit is provided under the Apache License 2.0.

Build

Install Buck and run the following:

    git clone --recursive https://gerrit.googlesource.com/gerrit
    cd gerrit && buck build release

Install binary packages (Deb/Rpm)

The instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

    apt-get update & apt-get install gerrit=<version>-<release>

NOTE: release is a counter that starts with 1 and indicates the number of packages that have been released with the same version of the software.

On CentOS/RedHat run:

    yum clean all && yum install gerrit-<version>[-<release>]

NOTE: release is optional. Last released package of the version is installed if the release number is omitted.
