refs https://sharp.pixelplumbing.com/api-utility#cache
- Sharp has a 50MB cache by default, used within libvips, to increase
the performance of transforming images
- this isn't relevant to us because we should never be optimizing the
same image as we check if the optimized image already exists
- I presume there is also some extra overhead of using the cache because
the memory doesn't seem to grow by 50MB
- the memory usage comparison in Ghost is pretty drastic - uploading 10
images in serial w/ jemalloc:
- with cache (default) = peak of 480MB, settles down to 330MB
- disabling cache = peak of 270MB, settles down to 161MB
- this commit disables the cache
- also adds stubbing for the function in tests
refs https://github.com/TryGhost/Ghost/issues/11944
- it's useful for consuming applications to know if images can be transformed outside of actually performing the transform (eg, when outputting "resized" image URLs)
- added `canTransformFiles()` that returns a boolean for whether or not `sharp` is installed
- mock non existant module util was defined twice
- split it out properly from the rest of the utils, update all references
- this allows us to move this util out of the codebase along with other code, e.g. the image manipulation code
no issue
- Updated Test & linting packages
- Updated use of hasOwnProperty
- Using Object.prototype.hasOwnProperty instead (ref. eslint.org/docs/rules/no-prototype-builtins)
- Removed already defined built-in global variable Intl
- Applied `--fix` with lint command on `core/test` folder
- The rules were broken because some of them were made stricter for `eslint: recommended` ruleset (ref. https://eslint.org/docs/user-guide/migrating-to-6.0.0#eslint-recommended-changes)
- Removed redundant global variable declarations to pass linting

Breaking changes for Ghost:
- no need to create a sandbox anymore, each file get's it's own sandbox
- just require sinon and use this sandbox
- you can still create separate sandboxes with .createSandbox
- reset single stubs: use .resetHistory instead of .reset
This is a global replace for any sandbox creation.

> Default sandbox
> Since sinon@5.0.0, the sinon object is a default sandbox. Unless you have a very advanced setup or need a special configuration, you probably want to just use that one.

* Refactored unsafeProcess to use unsafeResizeImage
* Removed CRAZY catch
closes#10144
- When the input image is well optimized and has smaller byte size than the processed one it's still being used
- Bumped sharp version to have access to `size` property
refs #4453
