Previously the key `git_ssh_url` was listed twice in the example payload of an Build Event web hook.

This adds a recurring Sidekiq job that removes up to 50 000 old web hook
logs per hour, if they are older than 90 days. This will prevent the
web_hook_logs table from growing indefinitely.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/46120

The st_commits and st_diffs columns on merge_request_diffs historically held the
YAML-serialised data for a merge request diff, in a variety of formats.

Since 9.5, these have been migrated in the background to two new tables:
merge_request_diff_commits and merge_request_diff_files. That has the advantage
that we can actually query the data (for instance, to find out how many commits
we've stored), and that it can't be in a variety of formats, but must match the
new schema.

This is the final step of that journey, where we drop those columns and remove
all references to them. This is a breaking change to the importer, because we
can no longer import diffs created in the old format, and we cannot guarantee
the export will be in the new format unless it was generated after this commit.

Add information on duplicate or multiple triggers caused by a slow response time.

Pipeline hook data now includes the project_id

Build was being triggered but there was no documentation about it, so
I'm adding what I was receiving from webhooks when implementing the
Rocketchat integration (https://github.com/PotHix/rocketchat-gitlab-hook).

This reverts commit 3e991230.

# Conflicts:
#	app/models/project.rb

Added "wiki" section and removed "repository"

I wanted to share what I learned trying to debug web hooks using
netcat.

Code is based on Project Webhooks, removing deprecations and without
commits listing.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/14660

See https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3103

This partially reverts commit 836d5930.

This was removed from the interface in
https://github.com/gitlabhq/gitlabhq/pull/6027 but its implementation
lingered around for two years.

- Add `avatar_url`, `description`, `git_ssh_url`, `git_http_url`,
  `path_with_namespace` and `default_branch` in `project` in push, issue,
  merge-request and note webhooks data
- Deprecate the `ssh_url` in favor of `git_ssh_url` and `http_url` in
  favor of `git_http_url` in `project` for push, issue, merge-request and
  note webhooks data
- Deprecate the `repository` key in push, issue, merge-request and
  note webhooks data, use `project` instead
