Resolve "Introduce round-robin project creation to spread load over multiple shards"

## What does this MR do?

Allow multiple shards to be enabled in the admin settings page, balancing project creation across all enabled shards.

## Are there points in the code the reviewer needs to double check?

* `f.select ..., multiple: true` isn't the most beautiful UI in the world, but switching to `collection_check_boxes` (or a facsimile thereof) isn't trivial
* Should `pick_repository_storage` be a method of `ApplicationSetting`, or `Project`? It's going to accrete logic over time so perhaps it should be its own class already?
* This is written to avoid the need for a database migration, so it is`serialize :repository_storage` without `, Array`. This is tested, but alternatives include:
  * Add a database migration
  * Write a custom Coder that will accept a String or Array in `load` and always `dump an Array.

Issues atom feed url reflect filters on dashboard

Makes the issue atom feed url reflect the selected filters on the issue dashboard page and project's issues page.

## Are there points in the code the reviewer needs to double check?

The solution isn't based on javascript and filters functionality but on the current url parameters. It didn't seem right especially when writing tests.

## Why was this MR needed?

After filtering the issues, users may press the feed button and see a different list of issues to what is shown on the HTML page

Merge branch '24017-long-build-list-dropdowns-which-scroll-are-not-immediately-obvious' into 'master'

change build list height to show 6,5 builds + improve padding of list, with firs…

## What does this MR do?

lets the builds dropdown in the pipeline graph show only 6,5 builds instead of 7.. so its easier to know if a user can scroll

## Are there points in the code the reviewer needs to double check?

I changed the padding of the list to 0 and gave the 8px top and bottom padding from the `ul` to the `first-child` and `last-child` li elements inside the list. Is that okey. Reason why, is that it breaks the list off correctly at the edges:)

## Why was this MR needed?

Add tip for using Chrome to run and debug teaspoon tests.

## What does this MR do?

Documents the approach I use when writing and debugging frontend tests, which is (IMHO) much better than running locally from the command line.

Ignore `builds` directory from eslint

Running `rake eslint` locally was including this directory reporting so many errors that are not from our source code.

See merge request !7279

Moved most of the functions that contained "window.doSomething" that were located at:
- app/assets/javascripts/application.js
To the following file:
- app/assets/javascripts/lib/utils/common_utils.js

The functions listed here:
- window.ajaxGet
- window.split
- window.extractLast
- window.rstrip
- window.disableButtonIfEmptyField
- window.disableButtonIfAnyEmptyField
- window.sanitize
- window.unbindEvents
- window.shiftWindow

Now will be accessible from the "gl.utils" namespace

eslint: Fix invalid filename validation

Attempt to fix the following error which is appearing in every new MR since `eslint-plugin-filenames` was introduced.

```
/builds/gitlab-org/gitlab-ce/app/assets/javascripts/gl_field_error.js.es6
  2:1  error  Filename 'gl_field_error.js.es6' does not match the naming convention  filenames/match-regex
```

This was happening because our ES6 files have the following structure `gl_hello_world.js.es6`. So `eslint-plugin-filenames` was considering as base name `gl_hello_world.js` which didn't pass the previous regex `^[a-z_]+$`

This new regex allows the following filenames to pass as valid:

- `gl_hello_world.js.es6` which base name translates to `gl_hello_world.js` 
-  `gl_foo_bar.js` which base name translates to `gl_foo_bar`
-  `d3.js` which base name translates to `d3` (especial case, maybe we should move this to the vendor dir and make the regex more specific)
