Remove dependency on Crayfish-Commons

[whikloj]

GitHub Issue: Islandora/documentation#2220
Resolves: Islandora/Crayfish-Commons#59

This PR relies on:

• Update dependencies chullo#99
• Cutting a version of https://github.com/Islandora/islandora-fedora-entity-mapper

What does this Pull Request do?

With the separation of the EntityMapper out into its own library, this PR removes the dependency on Crayfish-Commons.
It also handles some deprecations I ran across while doing this work.

What's new?

• Remove crayfish-commons and adds chullo and islandora-fedora-entity-mapper to the composer.json.

• Updates namespaces where necessary.

• Adds a Fedora Flysystem logger to inject to the container.

• Replaces deprecated \Symfony\Component\HttpFoundation\File\Mimetype\MimeTypeGuesserInterface with \Symfony\Component\Mime\MimeTypeGuesserInterface

• Does this change add any new dependencies? yes islandora-fedora-entity-mapper and chullo (though both were originally part of or pulled in by crayfish-commons)

• Does this change require any other modifications to be made to the repository
  (i.e. Regeneration activity, etc.)? no

• Could this change impact execution of existing code? If you are using another part of crayfish-commons, but I'm not sure what that would be

How should this be tested?

• Build a site with this islandora and see that you can the Fedora URIs displayed in Drupal are correct and correspond to the object in Fedora.
• Use this PR to build a new vagrant box with all the pieces - Upgrade 5.4 symfony and separate EntityMapper Islandora-Devops/islandora-playbook#263
