ImageProcessing gem is a wrapper around MiniMagick and ruby-vips, and
implements an interface for common image resizing and processing. This
is the canonical image processing gem recommended in [Shrine], and
that's where it developed from. The initial implementation was extracted
from Refile, which also implements on-the-fly transformations.
Some features that ImageProcessing gem adds on top of MiniMagick:
* resizing macros
- #resize_to_limit
- #resize_to_fit
- #resize_to_fill
- #resize_and_pad
* automatic orientation
* automatic thumbnail sharpening
* avoids the complex and inefficient MiniMagick::Image class
* will use "magick" instead of "convert" on ImageMagick 7
However, the biggest feature of the ImageProcessing gem is that it has
an alternative implementation that uses libvips. Libvips is an
alternative to ImageMagick that can process images very rapidly (we've
seen up 10x faster than ImageMagick).
What's great is that the ImageProcessing gem provides the same interface
for both implementations. The macros are named the same, and the libvips
implementation does auto orientation and thumbnail sharpening as well;
only the operations/options specific to ImageMagick/libvips differ. The
integration provided by this PR should work for both implementations.
The plan is to introduce the ImageProcessing backend in Rails 6.0 as the
default backend and deprecate the MiniMagick backend, then in Rails 6.1
remove the MiniMagick backend.

* Fix warning in railties test

There's no reason to block future versions of Capybara since we don't
_know_ they are going to break. How will we know if we have a
conservative option set? This change prevents us from blocking users who
want to upgrade in the future.
Somehow `test_config_another_database` didn't fail on CI, but it will
fail locally.

Although not a direct dependency, it's pulled in by Resque for
Active Job integration tests so we need to update because the
rack-protection gem has a security vulnerability[1].
[1]: https://nvd.nist.gov/vuln/detail/CVE-2018-7212
We locked Minitest to 5.11.1 in #31799
because 5.11.2 included a breaking change.
The change was fixed in 5.11.3, so we no
longer need to lock in the version.
Queue_classic currently limits pg to "< 0.20".
It is therefore not used for rails CI tests. There has been
a bull request for a while (by a co-worker of mine), which
fixes the incompatibilities and extends dependencies to pg-1.x.
This patch add this pull request to the Gemfile as an interim
solution, until it is merged.
