Replace islandora_defaults with an exported site islandora-starter-site

[lutaylor]

Overview

Intial work to replace https://github.com/Islandora/islandora_defaults with an exported site in a project housed in this repository https://github.com/Islandora/islandora-starter-site/.

The intent is to simplify expectations and maintenance. This is to help facilitate the communities end goal to modularize Islandora into largely independent Drupal modules that let Drupal sites pick and choose their repository features.

The structure of the example site could look like:

https://github.com/Islandora/islandora-starter-site/

-composer.json / composer.lock
-config/sync
-content/sync

Acceptance Criteria
-We have an islandora_defaults replacement exported starter site.
-Current enabled islandora_default functionality as installed with the Islandora Playbook in Olivero is present.
-README should contain instructions on how to manually utilize the starter-site outside of ISLE/playbook. README should specify awareness for existing sites.

Code cutoff is of commit 7b34ad2. Commits to Defaults after that (which affect functionality!) will need to be made separately on this repo

Just a note: Work had been started (#1) at the presently-latest release of 2.1.1 of islandora_defaults... Looking at the diff between it and the present unreleased HEAD of 7b34ad2: Islandora/islandora_defaults@2.1.1...7b34ad2 ... is fairly small stuff, pretty much:

• The Drupal version compatibility assertions (dropping 8)
• The resources_types URI change for the "Collection" term; and,
• The changing of the condition plugin in the repository_content context

... Notably, don't presently have an analog for existing action/CI workflow, as it has the project baked in and the like, which would require some reworking to use with this starter site approach.

Looks like I had already had the "Collection" term URI updated (slight goof in workflow having made it easier to grab the file from Github... which resulted in me grabbing it from islandora_defaults's HEAD, instead of from the 2.1.1 release).

Otherwise, effected the other two changes between https://github.com/Islandora/islandora-starter-site/pull/1/files/e4ef87debd5a755d01172cdb12dcc57e585c8d3c..4f94206d456f54c8fafc55275d2b425599f5b962
