Retries in Sidekiq and in the remote mirror scheduler can cause repeated
attempts in quick succession if the sync fails. Each failure will then
send an e-mail to all project maintainers, which can spam users
unnecessarily.

Modify the logic to send one notification the first time the mirror
fails by setting `error_notification_sent` to `true` and reset the
flag after a successful sync.

Taller letters like "g" were getting
slightly cutoff before.

`spec/features/uploads/user_uploads_file_to_note_spec.rb` was failing in
master because MySQL detected a deadlock when a DELETE and INSERT for
the same indexed item occurred within a transaction in the `uploads`
table.  Due to InnoDB's next-key locking algorithm
(innodb_locks_unsafe_for_binlog in
https://dev.mysql.com/doc/refman/5.5/en/innodb-parameters.html), InnoDB
sets an exclusive lock for any of the indexed records it encounters, so
the INSERT will fail until the DELETE is committed.

To fix this, we just disable the transaction for MySQL and keep
it for PostgreSQL.

Upgrades prettier to 1.15.3
Runs `yarn prettier-save-all` against the codebase
Most changes are due to https://github.com/prettier/prettier/pull/5519

This backports changes made in
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/9134.

In theory the case could happen that the initial linking of the pool
fails and so do all the retries that Sidekiq performs. This could lead
to data loss.

To prevent that case, linking is done before Gits GC too. This makes
sure that case doesn't happen.

- Add tests for project topics

GitLab Pages supports projects hosted under a subgroup, but not subgroup
websites. That means that only the highest-level group supports

i.e.:
You created a group for your engineering department called
`engineering`, a subgroup for all your documentation websites called
`docs`,and a project within this subgroup is called `workflows`.
Your project URL is `https://gitlab.com/engineering/docs/workflows/`.
Once you enable GitLab Pages for this project, the site will live under
`https://engineering.gitlab.io/docs/workflows`.

The importer would display a 500 error page if you attempted to import
using a non-existent DNS entry. This commit rescues known network issues
and consolidates them into
BitbucketServer::Connection::ConnectionError`.  The previous error
handling in the paginator doesn't work because it returns a lazy
collection.

1. Avoid suggestions being applied on the same file
from reverting previous changes
2. Gracefully use and handle file changes error
when updating the file (though, it does not totally
solves the sync problem for multiple suggestion
applications at once)

To reduce code duplication between CE and EE components,
creates a mixin with the common methods for the
graph component

Accidentally added a comma to the end of a list in ruby.

Allowing the EE to override a helper function to pass more data to vue

Here is another line that prettier changed in ee.

* Remove headerAction getter from job getters
* Remove prop from being passed into header_ci_component
* Remove no longer needed tests

Fetch a specific key's fingerprint instead of all fingerprints.
Check for the specific key by title and expected fingerprint.
This avoids the use of `all`, which can be unreliable.

Previously the nullification wasn't done, as the only caller would later
destroy the model all together. In
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/9070 this change
was made. This commit is basically a backport before that MR is merged.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/31910, https://gitlab.com/gitlab-org/gitlab-ce/issues/32588

We introduced releases_page feature flag.
Given this feature is deemed stable, we should remove
this flag before 19th.
