Make internal api work with full repo path and name

## What does this MR do?

Make internal api work with full repo path and name

## Why was this MR needed?

So we can pass full repository path on filesystem from gitlab-shell instead of extracted one. We need this for nested groups support where project is can be nested under several groups.

Create cycle analytics bundle

Pass user instance to Labels::FindOrCreateService or skip_authorization: true

## What does this MR do?

It fixes a bug described in #23694 when `project.owner` was passed to `Labels::FindOrCreateService`. `Labels::FindOrCreateService` expected a user instance and `project.owner` may return a group as well. This MR makes sure that we either pass a user instance or `skip_authorization: true`.

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

- places where we pass `skip_authorization: true`

This prevents VueJS being included in application.js & therefore included on everypage

Use optimistic locking

## What does this MR do?
Removes the usage of pessimistic locking in favor of optimistic which is way cheaper and doesn't block database operation.

Since this is very simple change it should be safe. If we receive `StaleObjectError` message we will reload object a retry operations in lock.

However, I still believe that we need this one: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/7005 as this will reduce a load on Database and FS.
This changes a behavior from:

### Pesimistic locking (previous behavior)

#### For updating
1. SELECT * FOR UPDATE (other updates wait on this)
2. we update ci_pipeline
3. latest_build_status
4. enqueue: (use: transition :created -> :pending)
5. [state_machine] we are in  state created, we can go to pending
6. [state_machine] ci_pipeline.status = created
7. [state_machine] ci_pipeline.save
8. [state_machine] after_transition: (if for success): PipelineSuccessWorker on Sidekiq
9. release DB lock

#### If no update is required
1. SELECT * FOR UPDATE (other updates wait on this)
2. we update ci_pipeline
3. latest_build_status
4. we are in pending, we can't transition to pending, because it's forbidden
5. release DB lock

### Optimistic locking (implemented by this MR)

#### For updating
1. latest_build_status
2. enqueue: (use `transition :created -> :pending`)
3. [state_machine] we are in state created, we can go to pending
4. [state_machine] ci_pipeline.status = created
5. [state_machine] ci_pipeline.save
6. [state_machine] [save] where(lock_version: ci_pipeline.lock_version).update_all(status: :created, updated_at: Time.now)
7. [state_machine] [save] unless we_updated_row then raise ObjectInconsistentError

#### If no update is required
1. we update ci_pipeline
2. latest_build_status
3. we are in pending, we can't transition to pending, because it's forbidden

## Why was this MR needed?
We have been seeing a number of problems when we migrated Pipeline/Build processing to Sidekiq. Especially we started seeing a lot of blocking queries.

We used a pessimistic locking which doesn't seem to be required. This effectively allows us to fix our issues with blocked queries by using more efficient method of operation.

## What are the relevant issue numbers?
Issues: https://gitlab.com/gitlab-com/infrastructure/issues/623 and https://gitlab.com/gitlab-com/infrastructure/issues/584, but also there's a bunch of Merge Requests that try to improve behavior of scheduled jobs.

Delete issue board welcome cookie

## What does this MR do?

This was seen in the idea to production demo, because the project had already existed on the exact same URL the cookie already existed which meant the blank state wasn't shown. 

This MR deletes the cookie on project create.

Replace static fixture by generated one in issue_spec.js

## What does this MR do?

- clean up `issue_spec.js`
- introduce an alternative approach to #19445
  - rename `rake teaspoon` to `rake teaspoon:tests`
  - introduce `rake teaspoon:fixtures` which generates fixtures using RSpec
  - introduce `rake teaspoon` which runs `rake teaspoon:fixtures` and `rake teaspoon:tests`

## Why was this MR needed?

- many duplications
- missing existence checks
- missing conditions
- static fixtures don't match real views

## Reasoning

I want to explain some of my decisions here, so that they stay visible for future discussions.

### Why not HAML?

- same number of HAML templates as number of fixtures (many input files)
- embedded logic less readable
- can not be rendered by JavaScript (because of inline Ruby)

### Why RSpec?

- real controllers for fixtures
- spys available for mocking
- easily report failed fixture generations

### Why not magic_lamp? (#19445)

- introduces another dependency/tool
- needs to run a server concurrently to teaspoon
- makes it harder to use a JavaScript test runner
- static HTML files serve faster
