Improve discussion rendering performance

Closes #51506

See merge request gitlab-org/gitlab-ce!22935

Chrome and other browsers ignore autocomplete=false and autocomplete=off
now. This causes the mirroring section to expand whenever a user clicked
"Expand" in the Repository settings.

https://developers.google.com/web/fundamentals/design-and-ux/input/forms/?hl=en
recommends using new-password as the new field to prevent automatic
filling.

It looks like we already do this in app/views/shared/_field.html.haml.

Or otherwise do not try to write repo config.

There is no need to make a difference between a Group or User
namespace, so also no need to define the classes of those.

And run in intervals.

In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/16027 it was
added to write `gitlab.fullpath` in the git config of all
repositories. But this only writes them on move or migrate to hashed
storage.

This adds a migration that writes the fullpath to all the
repositories.

Correctly handle data-loss scenarios when encrypting columns

Closes #53763

See merge request gitlab-org/gitlab-ce!23306

If the EncryptColumns background migration runs in a sidekiq with a
stale view of the database schema, or when the purported destination
columns don't actually exist, data loss can result. Attempt to work
around these issues by reloading schema information before running
the migration, and raising errors if the model reports that any of its
source or destination columns are missing.

This assignment is only used by the Projects::NetworkController, so
we're needlessly assigning this very generically-named instance variable
on every controller which includes `ExtractsPath`, which is quite a few.

Further, the way we were passing this hash to
`HashWithIndifferentAccess` caused the following deprecation warning
after upgrading to Rails 5:

    DEPRECATION WARNING: #to_hash unexpectedly ignores parameter
    filtering, and will change to enforce it in Rails 5.1. Enable
    `raise_on_unfiltered_parameters` to respect parameter filtering,
    which is the default in new applications. For the existing
    deprecated behaviour, call #to_unsafe_h instead. (called from new at
    lib/extracts_path.rb:116)
