* show commits count in the merge request version dropdown

* Add merge_request_diff validation to merge_request model
* Improve initialize of merge_request_diff object
* Rename some merge_request_diff methods for clarity
Signed-off-by: Dmitriy Zaporozhets <dmitriy.zaporozhets@gmail.com>

Since MergeRequestDiff is not about branches and current state of merge
request diff anymore I removed most of branch related method and added
validation for head/start/base commit sha. From this point
MergeRequestDiff is about saving diff between branches only once at moment of
creation. Once created MergeRequestDiff should not be changes. Because
of that we should not rely on changes in source/target branches when
read from MergeRequestDiff

fix TODO comment

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/20376

webhooks: include old revision in MR update events

## What does this MR do?

Includes the old revision for an MR in webhooks.

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

The docs do not give an example `update` hook; should I add one?

## Why was this MR needed?

In order to keep web hook listeners stateless, it helps to include the previous revision of the MR in the hook so that it does not need to remember the last revision (which may also be wrong in case of missed or out-of-order events due to previous errors).

## What are the relevant issue numbers?

N/A

Use fewer queries for CI charts

## What does this MR do?
It reduces number of queries sent for aggregating counts for CI graphs.

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

## Why was this MR needed?
For this project (gitlab-ce), loading `/graphs/master/ci` is so slow it times out eventually. I did a quick benchmarking on production and found that it can take 72.5 seconds to only load the controller action variables (there are queries done from the view, didn't look into those). This MR reduces the time to about 2.5 seconds.

Extra improvement could be done by introducing an index on `gl_project_id` and `created_at` for `ci_builds` table, but I can't confirm that right  now.

## What are the relevant issue numbers?
