Add support for Keycloak. Implements #39

[joostdecock]

Change Summary

This adds support for Keycloak SSO, which closes #39

I have also added an extra section to the README with info that I found was (too) hard to find:

• Supported authentication methods
• How to deal with some common challenges when running in Docker

If that is unwanted, I can re-submit without the README changes.

Thank you for the PR @joostdecock!

I'd prefer for the text you've added to the README to be alongside the rest of the documentation, so it's all in one place.

Could you cut/paste it at the bottom of this page: https://typesense.org/docs/guide/docsearch.html (You'll find an edit button at the bottom of the page).

@jasonbosco sure thing:

• Submitted a PR for the docs: https://github.com/typesense/typesense-website/pull/177
• Reverted the changes to the README in this PR

@joostdecock Thank you! I've published your updates in typesense/docsearch-scraper:0.7.0.rc1. Could you give it a shot and confirm that it works as expected?

[joostdecock]

@jasonbosco it seems to be missing the dependency:

Traceback (most recent call last):
  File "/usr/lib/python3.10/runpy.py", line 196, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "/usr/lib/python3.10/runpy.py", line 86, in _run_code
    exec(code, run_globals)
  File "/home/seleuser/src/index.py", line 8, in <module>
    from keycloak.realm import KeycloakRealm
ModuleNotFoundError: No module named 'keycloak'

Oops, I missed a build step. Could you try again with typesense/docsearch-scraper:0.7.0.rc2?

[joostdecock]

@jasonbosco Sorry for the delay, I had some unexpected health issues, but the dependency issue is fixed in rc2 👍

[jasonbosco]

Thank you for confirming @joostdecock. I just published typesense/docsearch-scraper:0.7.0.

Hope you're feeling better now.
