Use password field defaults for services

Previously we masked the password field manually. After the refactor that services page received we can use `password_field` default masking.

Fixes internal https://dev.gitlab.org/gitlab/gitlab-ee/issues/314

Add dropdown to quickly create issue or branch from project page

because just 'new issue' link is not valid for all users. A lot of people use external issue tracker. So I grouped several links under one button

This merge request has no screenshot because it brings no visual change. Its about action.

Only enable HSTS header for HTTPS and port 443

### What does this MR do?

This MR adds a check that the port used is 443, in addition to HTTPS being enabled, when activating the HSTS header.

### Why was this MR needed?

If a user is using a non-standard port for SSL, enabling this header would send clients to port 443 when that port is invalid.

### What are the relevant issue numbers?

Closes https://github.com/gitlabhq/gitlabhq/issues/9449

Better handle unknown projects and groups for autocomplete

While working on !963, I noticed that specifying an unknown project ID or group ID would cause an error in the controller. This MR improves on the handling of unknown projects or groups:

1. If the user is authenticated, return a blank JSON with a 404 error.
2. Otherwise, redirect the user to login so we don't leak information about whether certain projects/groups exist.

Do not add the same icon multiple times to dropzones

Some DOM queries were to broad which caused paperclip icons and spinners
to be added multiple times to a dropzone in case of multiple dropzones
on a page.

![gitlab-dropzone-icon-bug](https://gitlab.com/dgerhardt/gitlab-ce/uploads/23e558a375cece21cc7af410e3839e05/gitlab-dropzone-icon-bug.png)

Steps to reproduce:
1. Open an existing issue or merge request with comments.
2. Move a file over the new comment dropzone. One paperclip icon should appear.
3. Now click the edit button for an existing comment and repeat step 2. You should see two paperclips.

Fixes #1725.
