Codestyle changes to easy EE merge

Add more parameters to the filter_parameters config.

Adds Sentry DSN, Webhooks, Deploy Keys, etc.

Alphabetized the parameters and included line breaks between each parameter. Easier to merge into EE if there are any differences.

This also seems to be the more popular syntax for adding new parameters, from what I can find.

In the future we may want to [increase the specificity of some of these](http://blog.bigbinary.com/2016/03/07/parameter-filtering-enhacement-rails-5.html) once Rails 5 is out. e.g. instead of `:hook`, `"hook.url"` would be just as effective without removing potentially useful information from the logs.

Cleaned up/tweaked Project#open_branches

See commit c825404572040a3a45cb9e2b3d3e7d64900f66c9 for the details of the changes and https://gitlab.com/gitlab-org/gitlab-ce/issues/14280#note_4973648 for more information.

See merge request !3985

This changes 4 things:

1. Project#protected_branches_names has been renamed to
   Project#protected_branch_names.

2. Project#open_branches uses a Set for the branch names as checking
   values in a Set is faster than checking values in a (large) Array.

3. Some redundant code in Project#open_branches has been removed.

4. Project#protected_branch_names now uses #pluck instead of #map,
   removing the need for loading entire DB records into memory.

Fix some broken links in the documentation [ci skip]

This changes Project#protected_branch? to use a query to check if a
branch is protected, instead of loading all ProtectedBranch records into
memory just to check if the list of names includes a given branch name.

Upgrade Doorkeeper from 2.2.2 to 3.1.0

I’d rather upgrade one major version at a time, so Doorkeeper needs to
be upgraded to 3.x before it can be upgraded to 4.x (which includes
Rails 5 support).

Changelog:

Working toward #14286.

Removes duplicates from the label dropdown

It concats the duplicate labels into a single label in the dropdown with the color being a gradient of the differnet colors being concatted.

I liked your idea @jschatz1 of using a standard icon color. However, with this i've taken all the duplicated colors & made a little gradient with them so it still half resembles the label colors (this has been limited to 4 or it could get crazy!)

Support supressing text file diffs on the default branch with .gitattributes

This change allows users to suppress diffs for text files by adding an entry to the `.gitattributes` file. To take effect the file present at the HEAD of the default branch.

When rendering a diff, if the file is text according to the charlock holmes gem (via the `text?` method) but the file is not diffable according to the project repository, then a message is displayed stating that the diff was suppressed.

![image](/uploads/2e119b725875a301e30d9ad482e283b3/image.png)

I looked into ways to do this using a `binary` flag as suggested by @stanhu in [this comment](https://gitlab.com/gitlab-org/gitlab-ce/issues/2315#note_4435454), however, there was no good way to seperate what was a real binary file from one that had been marked as not diffable in `.gitattributes`.

Fixes and closes gitlab-org/gitlab-ce#2315.

See merge request !3806

This is a combination of 3 commits.

- Update the bare repositories info/attributes if the default branch is updated
- Check the diff attributes of a file before showing a diff
- Update CHANGELOG

Load the "New Branch" button asynchronously

Here's how it looks like for logged in users:

And here it is for anonymous users (or when a new branch can't be created by a logged in user):

Project deploy keys updated UI

Closes #13992

See merge request !3912

This button depends on Issue#can_be_worked_on? which in turn depends on
Issue#related_branches. By rendering this button asynchronously we can
finally remove all usages of Issue#related_branches and
Issue#referenced_merge_requests from the issues "show" page.

Enable the UrlFormat and UrlQuotes SCSS Linters.

There were no lints to fix for this one, so it's just preventative.

UrlFormat: URLs should be valid and not contain protocols or domain names.

UrlQuotes: URLs should always be enclosed within quotes.
