Recalculating graph_log took minutes on a large repository since each
of the 6000 commits would need to calculate the diff. Since graph_log
does not appear to be used, remove it from the list of things to update.
For the Linux kernel repository, this reduced the ProjectCacheWorker time
from 8+ minutes to 16 seconds.
Closes#2016
Advanced cache
Fixes#1993
* Build missing cache values in background job after each push
* Store commit_count in project table. Refresh in background job
* moved repository size calculation in background job
## Advantages
Every time push is triggered - we build cache for project even without user visiting project page.
That means first visit is as fast as others now. This is especially good for active projects where people have some requests fast because of cache and some slow - because cache was build in their request.
Between cache expired and cache built we we had gap when Linux repo can give 502 error because calculation commits count takes 30 seconds or even more.
Using value from database fix this problem. Before cache is updated you see old value from database. After - you see new one.
Basically this merge request is super win to GitLab. We don't do some heavy operations in user request but instead in background job.
## Temporary problem
After this migration all projects will have `0` commits in database. It fill be replaced with real value on next push. I did not add recalculation to migration because it will last forever on big instances. Can be fixed by adding rake task which will go in background on live instance without downtime

Fix mentions not being created upon issue/merge request update
New cross-references weren't being added when they were made in an issue or merge request update.
This happened because the relevant `UpdateService`s were making the `notice_added_references` call
after the model had already been updated and saved, so the `changes` attribute was empty and no
cross-references were made at all.
This fixes the bug and adds a bit of testing and a bit of refactoring.
Closes#1773

Use password field defaults for services
Previously we masked the password field manually. After the refactor that services page received we can use `password_field` default masking.

Only enable HSTS header for HTTPS and port 443
### What does this MR do?
This MR adds a check that the port used is 443, in addition to HTTPS being enabled, when activating the HSTS header.
### Why was this MR needed?
If a user is using a non-standard port for SSL, enabling this header would send clients to port 443 when that port is invalid.
### What are the relevant issue numbers?
Closes https://github.com/gitlabhq/gitlabhq/issues/9449

Implement faster search of code (via git grep)
Much faster than iterating over each file using rugged.
Performance compare for Linux repository using keyword `sha`:

OLD: 250 seconds
NEW: 9 seconds
