ReviewersUtil: Increase multiplier for candidate list to 3

Since the frontend reduced the number of suggested reviewers to 6 [1] we
have users complaining about users being missing in the reviewer
suggestion. This is because the account query to compute the reviewer
candidates is limited to 2 x <limit-from-the-request>, which is 12 now.
If there are more than 12 matches some accounts are dropped, which may
contain the account that the user expects. In the case I debugged there
were 15 candidates, out of which only 2 are suggested in the end. When
the limit is set to 12, 1 of them got dropped.

Increasing the multiplier for the candidate list to 3 shouldn't have bad
impacts on the performance, basically 3 * 6 = 18 is still lower than the
limit that we used before [1], 2 * 10 = 20, and that limit worked well.

Gerrit Code Review

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

Build Status

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.

Build

Install Bazel and run the following:

    git clone --recurse-submodules https://gerrit.googlesource.com/gerrit
    cd gerrit && bazel 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>]

On Fedora run:

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

Use pre-built Gerrit images on Docker

Docker images of Gerrit are available on DockerHub

To run a CentOS 7 based Gerrit image:

    docker run -p 8080:8080 gerritforge/gerrit-centos7[:version]

To run a Ubuntu 15.04 based Gerrit image:

    docker run -p 8080:8080 gerritforge/gerrit-ubuntu15.04[:version]

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