Feat: add sso_auth parameter

[QuentinBtd]

Why ?

sso_auth parameter exists in Priutnl servers.
When set at true, it will require client to authenticate with single sign-on provider on each connection using web browser.
It could be usefull to have it. (And I need it, of course)

How ?

Adding it in provider.

Bonus

Update pritunl docker image version.

Hello @disc 👋

Hey @QuentinBtd, i appreciate your contribution, but I think it won't work without configuration of SSO settings for the whole pritunl instance (see the attached screenshot).

I started to work on the instance settings some time ago here () but haven't completed it yet.

[QuentinBtd]

Do you think Pritunl will return an error if the provider send a JSON with sso_auth in, while SSO is not configured at the instance level?

I could try it with an instance where SSO is not configured 😃

I meant it won't work without a configuration of SSO for the entire server, but the options sso_auth will be saved and will open browser each time with 404 page due to empty SSO settings.

This feature could not be useful if you manually setup SSO on the server but manage the sso_auth option with terraform, don't you think so?

That's exactly what I want to do 👍

The SSO configuration is already present on my instance. My servers are provisioned via Terraform but I have to manually check sso_auth after each apply terraform because this action unchecks it 😢

Add test case for a new option

Got you, lets add a test for the new option and fix small issues that I left.

@QuentinBtd I'm going to close this PR as a duplicate, because I've just merged another PR with a support of the same option sso_auth #48

No problem
@SwissGipfel was more fast than me, or have more time, but thank you ❤️
