Add wbr style for IE11 compatibility

See merge request gitlab-org/gitlab-ce!27846

Unlike uploads that have been uploaded with Tempfile, the project
import/export archives are stored in a temporary cache directory and
remain there if:

1. Object storage is enabled
2. `move_to_store` is set to `true`.

CarrierWave will leave these files there until disk space runs out or a
clean step is run manually.

If `move_to_store` is set to `false`, CarrierWave will remove the files
after storing them. However, unlike a local file, with object storage,
the file is still copied, so setting `move_to_store` to `true`
doesn't buy us anything.

To ensure files are cleaned up, we can just inherit from the
GitlabUploader implementation of `move_to_store`, which returns `true`
if it's a local file, `false` otherwise.

Fix update head pipeline process of Pipelines for merge requests

See merge request gitlab-org/gitlab-ce!28057

If the UI sends a string value for lock_version (e.g. "0"), then the
previous monkey patch did not properly handle that properly. This
commit casts the value to an integer to determine whether to look for
NULL lock_versions.

For merge requests, GitLab sends a POST request to
`namespace/project/merge_requests/:iid` with the
`merge_request[lock_version]` parameter with a string `0`. The string
value comes from the form field, which explains why
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28145 wasn't
sufficient.

[CE] Compute resolver complexity based on items

See merge request gitlab-org/gitlab-ce!28017

If a field is a resolver, its complexity is automatically
increased. By default we add extra points for sort and search
arguments (which will be common for various resolvers).

For specific resolvers we add field-specific complexity, e.g.
for Issues complexity is increased if we filter issues by `labelName`
(because then SQL query is more complex). We may want to tune these
values in future depending on real-life results.

Complexity is also dependent on the number of loaded nodes, but only
if we don't search by specific ID(s). Also added complexity is limited
(by default only twice more than child complexity) - the reason is
that although it's more complex to process more items, the complexity
increase is not linear (there is not so much difference between loading
10, 20 or 100 records from DB).

Try to simplify feature flag checks by using policies

There are two cluster hierarchies one for the deployment platform and
one for controllers. The main difference is that deployment platforms do
not check user permissions and only return the first match.

Instance level clusters were already mostly supported, this change adds
admin area controllers for cluster CRUD
