Fix transient failure on AnalyticsBuildEntity

AnalyticsBuildEntity uses `Time.now` to calculate durations, and on slow running builds could fail this spec. Mocking with `Timecop` should be sufficient to fix this.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/25500

Explicitly declare all javascript globals and all eslint rule violations

This merge request takes every single external global variable referenced within a javascript file and explicitly marks it with a `/* global Foo */` comment block at the top of the script.

This also expands all blanket instances of `/* eslint-disable */` with an explicit list of disabled rules.  This is useful because if we need to search for violations of a particular rule we can simply grep the codebase for something like `no-unused-vars` or `semi` and find all of the places where this rule has yet to be fixed.

Lastly, it also removes and resolves any existing `no-undef` eslint violations.  This is useful for catching mistakes like forgetting to declare a variable with `var`/`let`/`const` which can cause hard to find bugs.

## What does this MR do?

1. Looks for generic uses of `/* eslint-disable */` and refactors them into individual rule exceptions.
2. Looks for all occurrences of `/* eslint-disable ... no-undef */` and resolves them by either fixing bugs or declaring globals with `/* global Foo */`.

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

This touches a lot of files, most changes touch nothing other than comment blocks or whitespace.  The exceptions are the following 14 files which required some small bug fixes after removing `no-undef`:

- api.js
- breakpoints.js
- build.js
- commits.js
- diff_notes/components/jump_to_discussion.js.es6
- gfm_auto_complete.js.es6
- gl_dropdown.js
- groups_select.js
- importer_status.js
- namespace_select.js
- notes.js
- preview_markdown.js
- projects_list.js
- single_file_diff.js

## Why was this MR needed?

Introduce deployment services, starting with a KubernetesService

## What does this MR do?

Adds a minimal `KubernetesService` and introduces the idea of deployment services, generally.

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

## Why was this MR needed?

Two issues scheduled for 8.15 both require a Kubernetes service - #22864 and #23580 - but they use it for very different things. Add a minimal kubernetes service to avoid conflicts later.
