Disable warming of the asset cache in Spinach tests under CI

I suspect some combination of Knapsack tests cause no regular Rack tests
to be loaded (i.e. all JavaScript tests), which leads to the error:

ArgumentError: rack-test requires a rack application, but none was given

In CI, we precompile all the assets so there is no need to warm the
asset cache in any case.

Closes #23613

Don't use Hash#slice since it's not supported in Ruby 2.1

There is currently a build failure in `master` and this MR fixes it. The issue was introduced by !6879.

The problem is that `Hash#slice` doesn't exists in Ruby 2.1. I've created an issue to take care of the other places we're using `Hash#slice`: #23590

Fix GitLab project import when a user has access only to their default namespace

## What does this MR do?

It fixes a bug when a namespace ID was not passed to `/import/gitlab_project/new` page. It occurred when a user have no choice of the namespace, so we did not render the input for namespace ID. This MR introduces a hidden input for the described case.

Update duration at the end of pipeline

## What does this MR do?
Moves duration calculation to be done only once at the end of pipeline processing.
Currently this is done every one build.

## Why was this MR needed?
This is the simplest thing that we can do before properly implementing duration calculation: https://gitlab.com/gitlab-org/gitlab-ce/issues/23523#note_17145614

Render HipChat notification descriptions as HTML instead of raw markdown

## What does this MR do?

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/1621 for issues, merge requests and comments.

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

This MR is small enough to double check everything.

## Why was this MR needed?

Because seeing raw markdown in HipChat notifications is not nice :)

Fix a 500 error viewing an MR with a deleted source project

## What does this MR do?

Allows merged MRs to be shown without any 500 errors if the source project is removed

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

https://gitlab.com/gitlab-org/gitlab-ce/commit/31c37c6c38258684fc92e0d91119c33872e39034 fixed this for closed MRs only. I had trouble understanding the introduced helper and logic, so reverted it and keyed everything on the existence of the source project or branch directly.

commits.json returns a 500 error for a closed or merged MR; the approach taken in the above MR was to hide the commits... tab, so I've run with that.

For merged MRs, the commits (but not the pipeline data) are in the target project, so we *could* do better, but it's a fairly nasty intervention to make it happen.

## Why was this MR needed?

Viewing merged MRs should work even if the fork they came from has been deleted or unlinked.

Add tooltip with jobs full name to pipelines graph

## What does this MR do?

This MR adds a tooltip to build items in the pipelines graph as some build names are truncated.

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

## Why was this MR needed?

Some job names that are truncated need to be fully identified to avoid confusion.

Render a hidden field with namespace ID so it can be read by JavaScript
and passed to "/import/gitlab_project/new" screen.

Refactor the spec file:
- remove hardcoded record IDs
- avoid top-level let if not used in all scenarios
- prefer expect { ... }.to change { ... }.from(0).to(1) over checking
that there are no records at the beginning of the test

Change input order on Sign In form for better tabbing.

## What does this MR do?

This unreverts 8751491b, which was mistakenly reverted in !6328. It also changes the implementation of the original commit to work with the new login styling and markup.

* upstream/master:
  Restrict ProjectCacheWorker jobs to one per 15 min
  Removed code from project members controller
  Make label API spec independent of order
  Refactoring find_commits functionality
  Differentiate the expire from leave event
  Remove pagination description from individual doc
  Fix a broken table in Project API doc
  Create project feature when project is created
  Simpler arguments passed to named_route on toggle_award_url helper method
  Fixed height of issue board blank state

The `class` and `data-*` attributes are meaningless in HipChat, and it
would probably be better to limit the tags, too. For example, we could
avoid block-level elements in `render_line`.

"pipeline: :single_line" leaves the protocol/host part out of the URLs
and caches them that way. To avoid giving those out to HipChat, markdown
is always rendered with "pipeline: :email" first.

There must be a better way to do this, but I can't see how to avoid the
link caching.

Using "pipeline: :email" gets "only_path: false" into the context to
produce full URLs instead of /namespace/project/...

Restrict ProjectCacheWorker jobs to one per 15 min

## What does this MR do?

This restricts performing ProjectCacheWorker jobs to once every 15 minutes per project. The goal of this is to reduce disk load in the event of a lot of pushes happening in a short period of time. 

The impact is that cached data (e.g. commit count) may be updated less frequently. Furthermore it could mean that separate push payloads won't lead to e.g. READMEs being updated. Most of the cached data isn't updated very frequently, so this trade off should be worth it considering the alternative is a burning storage layer. 

In the future we'll have to flush caches in a smarter way. For example, refreshing the README cache could probably be done separately from the other caches with its own lease and such. See https://gitlab.com/gitlab-org/gitlab-ce/issues/23550 for more information.

This patch makes sure GitLab does not save the refs to the filesystem
each time the deployment is updated. This will save some IO although I
expect the impact to be minimal.
