Ci::Commit becomes a Pipeline object
1. Ci::Commit receives context: ref, :tag.
1. One Ci::Commit describes a one Pipeline
1. Pipeline is created from `.gitlab-ci.yml`
1. Pipeline is a ordered group of builds
1. We test MR against Pipeline
1. Pipelines have a separate view (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3703)
1. Pipeline can be triggered from UI (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3703)
1. Later we change `Trigger -> TriggerRequest -> Build` to `Trigger -> Pipeline` (future)
1. We add a Pipeline Hook that will be triggered on Pipeline status change (future)
1. We extend notifications to use `Pipeline Hook` to send summary on pipeline changes (future)
After merging that I'll prepare a separate MR that will unify naming, database columns, table names:
```
Ci::Commit -> Pipeline
Ci::Build -> Build
CommitStatus -> Job
GenericCommitStatus -> ExternalJob
ci_commits -> pipelines
ci_builds -> jobs
```
This MR implements first 5 points.
This is made to solve this issue https://gitlab.com/gitlab-org/gitlab-ce/issues/14149.

add slack notifications for wiki pages
## What does this MR do?
Lets the Slack service be configured to send notifications when wiki pages are created or edited.
## Are there points in the code the reviewer needs to double check?
I'm just starting to get familiar with the Gitlab codebase and I was unsure on how to get the wiki page url to pass it to the slack message, on whether or not I needed to refactor the create/update methods for wiki pages from the controller to a service (but seemed necessary to test it better), and if I needed to add a column to the web hooks table or if the services table would have been enough. Please let me know if I should change anything and I will improve the MR, thanks for checking :)
## Why was this MR needed?
Related to #563 and fixes#4233.

Sanitize branch names for confidential issues
- When creating new branches for confidential issues, prefer a branch name like `issue-15` to `some-sensitive-issue-title-15`.
- The behaviour for non-confidential issues stays the same.
Closes#14566
See merge request !3671
Start with iid on branch creation
After the discussion it in #3886 it was decided the iid should be in the beginning of the branch name.

Fix trailing slash in teamcity_url
Originally opened at !2309 by @ctmay4.
As described in #3515, if you have trailing spaces in the the Teamcity server name, the service
will not work properly. Switching from `URI.parse` to `URI.join` fixes it so that it works with
or without a trailing slash.
Fixes#3515.
See merge request !3679
To reproduce:
1. Create a project with some content
2. Rename the project
3. Create a new project with the same name.
4. Boom - 404.
After step 2, the branch and tag counts were not being cleared. This would
cause `repository.has_visible_content?` to erroneously return `true`
for the newly-created project.
Closes#13384
