This is needed to support creating/dumping/loading indexes that use the
gin_trgm_ops operator class on PostgreSQL. These changes are taken from
Rails pull request https://github.com/rails/rails/pull/19090.
The pattern in the `::reference_pattern` class method in the
ExternalIssue model does not match all valid forms of JIRA project
names. I have updated the regex to match JIRA project names with numbers
and underscores. More information on valid JIRA project names can be
found here:
https://confluence.atlassian.com/jira/changing-the-project-key-format-192534.html
* The first character must be a letter,
* All letters used in the project key must be from the Modern Roman Alphabet and upper case, and
* Only letters, numbers or the underscore character can be used.
This particular setup had 3 problems:
1. Storing SQL queries as tags is very inefficient as InfluxDB ends up
indexing every query (and they can get pretty large). Storing these
as values instead means we can't always display the SQL as easily.
2. We already instrument ActiveRecord query methods, thus we already
have timing information about database queries.
3. SQL obfuscation is difficult to get right and I'd rather not expose
sensitive data by accident.
Storing of application metrics in InfluxDB
This adds support for tracking metrics in InfluxDB, which in turn can be visualized using Grafana. For more information see #2936.

Environment variables in the app
Fixes#3717 and #3519
## Why environment variables?
We need environmental variables, they are an expected way to configure apps https://medium.com/@kelseyhightower/12-fractured-apps-1080c73d481c#.ntrdiyu4c
This causes many tools and to tutorials to make it easy to set environmental variables and harder to supply a configuration file.
So even though we agree they are not ideal https://support.cloud.engineyard.com/hc/en-us/articles/205407508-Environment-Variables-and-Why-You-Shouldn-t-Use-Them the market has spoken.
## Why for GitLab the application and not for the Omnibus packages?
Environmental variables are also needed by people that do not run our Omnibus packages, for example natively bundled apps (Debian apt-get) and idiomatic Docker packages (Mesos, Kubernetes, etc.).
Of course it should work great with Omnibus packages too so any advise is welcome in that regard.
There is an MR https://gitlab.com/gitlab-org/omnibus-gitlab/merge_requests/575/diffs to be able to set any variable in gitlab.rb via environmental variables. I think both that and this MR should be merged to solve the configuration problem for both Omnibus and non-Omnibus installations. When both are merged the documentation should be crosslinked.
## Why uppercase?
Need to be all cap according to Google Shell guideline:
"Constants and Environment Variable Names => All caps, separated with underscores, declared at the top of the file."
https://google.github.io/styleguide/shell.xml#Constants_and_Environment_Variable_Names
Or as explained on http://stackoverflow.com/a/673940/613240
Keeping to this convention, you can rest assured that you don't need to know every environment variable used by UNIX tools or shells in order to avoid overwriting them. If it's your variable, lowercase it. If you export it, uppercase it.

Sidekiq-cron configuration moved to gitlab.yml
When `sidekiq-cron` was introduced, jobs configuration where placed
in `schedule.yml` file.
As discussed in #3928, this is not desirable.
We moved it to `gitlab.yml`, exposing only the "cron" part of the configuration.

Allow account unlock via email
We see a lot of users get confused about what it means when your account gets
locked. Many try to reset their password and are still faced with a lockout.
With this change, users receive an email that allows them to unlock their
account immediately. The previous behavior where the account is auto-unlocked
after a time also still works.
