Reduce number of queries made for merge_requests/:id/diffs

## What does this MR do?
It reduces the number of DB queries made while processing and rendering MR notes.

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

## Why was this MR needed?
For `https://staging.gitlab.com/gitlab-org/gitlab-ce/merge_requests/3142/diffs.json`, for each note we make number of DB queries, almost all of them are handled by the AR caching layer, but they seem to add up a few seconds. Testing on staging, calling `merge_requests/3142/diffs.json` was reduced to ~5.5 seconds from ~8 seconds.

## What are the relevant issue numbers?

Remove project which can't be pulled while seeding

This project can't be pulled from GH when running `SIZE=20 rake dev:setup`

Add a log message when a project is scheduled for destruction for debugging

We have a lot of projects that are in `pending_delete` state. It's not clear whether they were ever scheduled for destruction, or whether Sidekiq just dropped the job due to `MemoryKiller` or some other reason.

Also this will provide a record of which user destroys a project.

Implement #3243 New Issue by email

So we extend Gitlab::Email::Receiver for this new behaviour,
however we might want to split it into another class for better
testing it.

Another issue is that, currently it's using this to parse project
identifier:

    Gitlab::IncomingEmail.key_from_address

Which is using:

    Gitlab.config.incoming_email.address

for the receiver name. This is probably `reply` because it's used
for replying to a specific issue. We might want to introduce another
config for this, or just use `reply` instead of `incoming`.

I'll prefer to introduce a new config for this, or just change
`reply` to `incoming` because it would make sense for replying to
there, too.

The email template used in tests were copied and modified from:
`emails/valid_reply.eml` which I hope is ok.

Merge branch '20308-fix-title-that-is-show-in-the-dropdown-toggle-button-on-projects-branches' into 'master'

Fix the title of the toggle dropdown button

## What does this MR do?

Fix the dropdown-button toggle displaying the correctly title.

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

See if the title is displaying correctly and if the code is acceptable.

## Why was this MR needed?

When you choose `Last updated` it should display the title `Last updated` instead of `Recently updated`. This fix makes this correctly displays the title.

## What are the relevant issue numbers?
Closes #20308.

Reduce instrumentation overhead

## What does this MR do?

This MR reduces the overhead of instrumented methods. See the commit message of 905f8d76 for more information.

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

Not that I can think of.

## Why was this MR needed?

The overhead of method call instrumentation was too great.

Before when you choose the way of `sort` instead it display the title correctly it was just apply the humanize helper in sort value.

E.g.

When you choose `Last updated` it should display the title `Last updated` instead of `Recently updated`. This fix makes this correctly displays the title.

Change the implementation of the `link_to` `filter_branches_path`

- Change the value of the `params[:sort]` in `link_to`. E.g. instead of using `'recently_updated'` is now using `sort_value_recently_updated`.

- Change the values of the case in the `branches_sorted_by` method for the values it receives in the `params[:sort]` that are: `nil`, `'name'`, `'updated_desc'`, `'updated_asc'`.

This reduces the overhead of the method instrumentation code primarily
by reducing the number of method calls. There are also some other small
optimisations such as not casting timing values to Floats (there's no
particular need for this), using Symbols for method call metric names,
and reducing the number of Hash lookups for instrumented methods.

The exact impact depends on the code being executed. For example, for a
method that's only called once the difference won't be very noticeable.
However, for methods that are called many times the difference can be
more significant.

For example, the loading time of a large commit
(nrclark/dummy_project@81ebdea5df2fb42e59257cb3eaad671a5c53ca36)
was reduced from around 19 seconds to around 15 seconds using these
changes.

Add commit stats

## What does this MR do?
When getting commit by SHA in api it returns commit stats

## Are there points in the code the reviewer needs to double check?
Not sure about test I added do we need separate test or we can just shove stats assertion in test above

## Why was this MR needed?
So api users/clients can get statistics on single commit

## What are the relevant issue numbers?
#20307

## What does this MR do?

I need to add notes about Elastic on EE side. To not create ugly conflicts in the future and to not duplicate work I created it here first.

I followed this guide https://gitlab.com/gitlab-org/release-tools/blob/master/doc/release-candidates.md#gitlab-ce

Replace reject_blocked with reject_blocked! in skipped callbacks.

`reject_blocked!` was introduced in c9def945, I can't find any references to `reject_blocked` ever existing.

See merge request !5532

In Rails 4.2 and below, skipping callbacks (skip_before_action, skip_after_action, etc.) that use methods which do not exist will not throw any errors.

On the other hand, Rails 5 does. See https://github.com/rails/rails/pull/19029

After testing with Rails 5 I noticed there are some methods that don't actually exist (because they were renamed, usually), this fixes a few instances of those.

reject_blocked! was introduced in c9def945, I can't find any references to reject_blocked ever existing.

Submit new issues created via the WebUI or API to Akismet for spam check on public projects.

## What does this MR do?

Submit new issues created via the WebUI by non project members to Akismet for spam check.

## Why was this MR needed?

Support for Akismet was added only to the API with !2266. This MR builds on that functionality to also check issues submitted via the WebUI for spam.

## What are the relevant issue numbers?
