Fix Docker build for DSpace-CRIS backend

References

Cherry-picks / Ports the following Docker bug-fixes from DSpace to DSpace-CRIS

Description

This PR ports a number of Docker bug-fixes from DSpace to DSpace-CRIS (see above). These ports can be found in the first 13 commits in this PR.

In addition, it updates the Docker scripts for DSpace-CRIS usage & adds basic instructions to the README on how to get started. This is all in the final commit. DSpace-CRIS specific changes include:

Updates all default image tags to use "dspace-cris-7_x", just so they don't conflict with any default dspace-7_x images.
Ensures /dspace/etc/ is mounted in Docker since it stores the default CRIS layout configuration
docker-compose.yml updated to automatically run the required scripts to initialize entities for DSpace-CRIS.
DSpace-CRIS specific Solr cores are now being installed in Docker
Updated dspace/src/main/docker-compose/README.md to provide step by step instructions for starting up DSpace-CRIS in Docker.

WARNING: This Docker build for DSpace-CRIS is NOT meant for production. It is just for testing/development purposes.

Instructions for Reviewers

Test the DSpace-CRIS Docker installation by following steps in the README. They are copied here for reference:

First, build the backend Docker images:

docker compose -f docker-compose.yml -f docker-compose-cli.yml build

Second, start up the backend containers: In this example we are using a Docker project named "dcris7", but any name can be used.
```
docker compose -p dcris7 up -d
```
(Wait until it starts up. Check the logs in Docker Desktop or by using docker compose -p dcris7 logs -f)

Third, create an initial admin account: In this example, we are creating "dspacedemo+admin@gmail.com".

docker compose -p dcris7 -f docker-compose-cli.yml run --rm dspace-cli create-administrator -e dspacedemo+admin@gmail.com -f Demo -l Administrator -p dspace -c en

Fourth, initialize your DSpace-CRIS with the sample Community/Collection structure:

docker compose -p dcris7 -f docker-compose-cli.yml run --rm dspace-cli dsrun org.dspace.administer.StructBuilder -e dspacedemo+admin@gmail.com -f /dspace/config/sample-structure.xml -o -

Finally, initialize your DSpace-CRIS with the default CRIS Layout:

docker compose -p dcris7 -f docker-compose-cli.yml run --rm dspace-cli cris-layout-tool -f /dspace/etc/conftool/cris-layout-configuration.xls

At this point, it should be possible to use the DSpace-CRIS backend running at http://localhost:8080/server/. One way to do so is to run the Angular frontend and point it at the backend:
- Checkout the dspace-cris-2023_02_x branch of the DSpace-CRIS frontend
- Install prerequisites : yarn install
- Build it: yarn build:prod
- Create a simple config.prod.yml to point it at localhost:8080
```
rest:
  ssl: false
  host: localhost
  port: 8080
  # NOTE: Space is capitalized because 'namespace' is a reserved string in TypeScript
  nameSpace: /server
```
- Start it in production mode: yarn serve:ssr
- At this point, your locally running UI should be pointing at the backend running in Docker.
