Fix timeout issue for rake task gitlab:backup:create

This is a fix for a database timeout which can occur when the backup
create task is taking very long (1-2 hours).
It seems that ActiveRecord is loosing the connection after a hour
idleness and need to be reconnected before use.

Limit guest access builds

This is https://dev.gitlab.org/gitlab/gitlabhq/merge_requests/1942 for ce-stable

See merge request !1943

This solves https://dev.gitlab.org/gitlab/gitlabhq/issues/2646

1. This MR simplifies CI permission model:
    - read_build: allows to read a list of builds, artifacts and trace
    - update_build: allows to cancel and retry builds
    - admin_build: allows to manage triggers, runners and variables
    - read_commit_status: allows to read a list of commit statuses (including the status of a build, but doesn't allow to see a build details)
    - create_commit_status: allows to create a new commit status using API

2. I do make sure that the proper permissions are used in all places where the CI can be shown.

3. Add the `read_build` ability if user is anonymous or guest and allow_guest_to_access_builds is enabled.

4. Add CI setting: public_builds.

5. The artifacts specific permission are removed, since they are covered by `*_build`.

Updated omniuath-saml to the latest version.

Allow manual resize of js-autosize textareas

First, the autosize library was being too controlling and removed the
`resize` property from any elements to which it was attached, removing
the drag handle. We've disabled this behavior in the vendored library
and added a spec to prevent a regression during an upgrade.

Second, we detect (as best we can) when the user manually resizes an
autosize textarea, and then remove the autosize behavior from it and
increase its max-height.

This should allow for the best of both worlds.

Closes #12832

Expand Git instrumentation

Increase LFS objects size column

Fixes #12745

Increases the `size` column integer limit to an 8-byte integer. This allows for a max value of `9223372036854775807` which is 9,223,372,036 GB. That should do it 😃

I tested this by first reproducing the error (push a file larger than 2.1 GB). The error was:

```
RangeError (3145728000 is out of range for ActiveRecord::ConnectionAdapters::PostgreSQL::OID::Integer with limit 4):
  lib/gitlab/lfs/response.rb:232:in `store_file'
  lib/gitlab/lfs/response.rb:170:in `render_lfs_upload_ok'
  lib/gitlab/lfs/response.rb:51:in `block in render_storage_upload_store_response'
  lib/gitlab/lfs/response.rb:204:in `render_response_to_push'

  lib/gitlab/backend/grack_auth.rb:18:in `call_with_kerberos_support'
  lib/gitlab/backend/grack_auth.rb:8:in `call'
```

Then I ran this migration and pushed the file again. It uploaded successfully.
