What does this Pull Request do?

• Installs and configures search_api_solr 8.3
• Supports installing solr on its own server.

How should this be tested?

• Get the PR
• vagrant up
• Create content
• Verify that it gets indexed and returned

In addition, testing the following is helpful.

• Get the PR
• Modify or create the following playbook:

---

- include: bootstrap.yml
  tags:
    - bootstrap
- include: solr.yml

• deploy and check that solr has been correctly installed

Additional Notes:

Although the above works, " You are using outdated Solr configuration set. Please follow the instructions described in the INSTALL.md file for setting up Solr. " is being reported here: http://localhost:8000/admin/config/search/search-api/server/default_solr_server

Not sure what may be cause of error.

@Natkeeran The box provisions correctly, but after ingesting content, it seems to get indexed, but I can't search by title. Default results of searching an empty text field return the result, but not if i actually using the title text.

@Natkeeran title is included in the solr indexing config 🤷‍♂️ Weird.

Part of this PR has been merged; #126. Updating to 8.3 needs further review and would need a different PR. Thus closing this one.
