sso: Switch to django-axes >= 5.0
- Add explicit dependency on django-ipware >=3. django-axes >= 6 adds
only and optional dependency on django-ipware. Adding explicit dependency make
the behavior safer.

- Depend on django-axes >= 5 where the authentication backend and other features
are available. The new code won't work with older versions. The new approach
uses and authentication backend to deny access to the login form on lockout and
a middleware to redirect user to locked out form when limit of attempts have
been reached.

- Drop old code used for compatibility with django-axes 3.x.

- Suppress verbose and debug messages as django-axes is too chatty.

- Re-implment the CAPTCHA form entirely. In the old style, we have a login form
with CAPTCHA field. That would not work with the new django-axes authentication
middle. On submission of the form, auth.authenticate() will be called. This
call invokes various authentication backends include django-axes authentication
backend. This backend's behavior is to reject all authentication attempts when
the IP is listed in locked table. The new approach is to provide a simple
CAPTCHA form with just the CAPTCHA field. If the form is successfully
validated (correct CAPTCHA is provided), then the lock on the IP address is
reset. The user is then free to perform 3 more attempts to login.

- Update firstboot form to send the request parameter when using
auth.authenticate() method. This needed by Django axes' authentication method
which will be triggered.

Tests:

- Run tests on Debian Bookworm and Debian testing.

- Axes verbose messages and debug messages are not printed on the console when
running FreedomBox in debug mode.

- Only three invalid attempts are allowed at the login page. After the final
incorrect attempt, user is redirected to CAPTCHA page. Visiting the login page
using the URL works but entering the correct credentials still takes the user to
CAPTCHA page.

- CAPTCHA form appears as expected. Clicking the CAPTCHA images downloads the
audio file corresponding to the image. Incorrect CAPTCHA shows an error. Correct
CAPTCHA takes the user to login form where they are able to login with correct
credentials. Entering incorrect credentials 3 times will take the user again to
CAPTCHA page.

- Creating user account during firstboot works.

- Blocked IP address the IP of the client such as 10.42.0.1 and not the local IP
address 127.0.0.1 according the django-axes log messages. While one client IP
address is blocked, another IP is able to login to the same user account that
was attempted by the blocked client.

sso: Adjust URL to CAPTCHA page needed by Django security fix
Fixes: #2170.

Starting with Django 2.2.25, re_path behavior has changed. When the regular
expression ends with a '$', a full match is performed with the regular
expression. This breaks the behavior of how we are currently matching the locked
URLs for CAPTCHA based login forms.

Tests:

- All tests are done on Debian stable with Django 2.2.25 and on Debian unstable
with Django 3.2.10.

- Go to home page, click on login link. Enter wrong password three times.
CAPTCHA page is show with URL ending with /locked. Type the correct password and
login will be successful.

- Install tt-rss. Logout. Go to /tt-rss/, redirection will happen to login page.
Enter wrong password three times. CAPTCHA page is show with URL ending with
/locked. Type the correct password and login will be successful.

*: Use django.urls.re_path() instead of its alias url()
- In Django 2.2 django.conf.urls.url() is an alias to django.urls.re_path().

- In Django 4.0, url() function will be removed. On Django 3.2, it throws a
warning that this function will be removed in future.

Tests:

- Run unit tests with Django 3.2 and Django 2.2.

- With Django 3.2 there are no warnings when running unit tests and when running
FreedomBox Service.

- Visit a few affected apps with both Django versions.

sso: Fix conflict between urls of sso and captcha
django-simple-captcha's /refresh url's regex was matching anything that ends
with the word "refresh". This was clashing with sso/refresh. Changed the regex
for captcha's url to captcha/refresh.

sso: Fixes for regressions after adding captcha and axes
- Change sso refresh url to refresh-pubtkt since refresh was conflicting with
  captcha's image refresh url.
- Fix datetime.timedelta calculation for refresh interval. Now validity of
  ticket is 30 seconds as it was intended to be. It was wrongly set to 30 days
  earlier.

Add SSO using auth_pubtkt for 3 web apps
- Install mod_auth_pubtkt and generate public/private key-pair.

- Redirect user to login page if no cookie is presented.

- Add check for authenticated user for login page.

- Temporarily switched to DSA because of a bug in mod_auth_pubtkt
  which causes it to accept only DSA and not RSA. Also had to use SHA1
  instead of SHA256.

- Enabled SSO for Syncthing, Repro and TT-RSS.

- Using tokens to authorize by user groups.

- Generate keys during first boot.
