In some schema migrations pure database schema update machinery was misused for long running migrations that entirely unrelated to database schema upgrades. Most notably Schema_144 that migrating external ids to NoteDb and Schema_146 where all accounts were migrated from ReviewDb to NoteDb. How the code is currently organized, that approach only works for small to medium gerrit installation sites with couple of thousands users. This change adjusts the schema update connection management and pass in schema factory instead ReviewDb instance to the schema migration process. That way it is possible to open two new connections for each schema migration step: 1. migrate data 2. bump new schema version As the consequence of this refactoring big sites shouldn't run into wait timeout exception during schema migration process.

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.

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.
